How to build a strength training program for health and longevity

Originally published on April 12, 2023

A strength training program for health and longevity should build movement skill, speed, power, strength, and enough muscle to keep daily life well below your maximum effort. In Episode 217 of the WHOOP Podcast, Dr. Andy Galpin, professor of kinesiology at California State University, Fullerton, and director of the Center for Sport Performance, joins Kristen Holmes, Global Head of Human Performance, Principal Scientist at WHOOP, to explain how to train for that outcome.

Galpin breaks down how to define strength training, how to choose exercises, how hard sets should feel, how to progress from week to week, and how sleep and soreness shape recovery. He also explains why connective tissue, force production, and fast movement all matter if your goal is lifelong performance.

How should you define strength training if your goal is health and longevity?

Strength training is best defined by the adaptation you want, not by the equipment in your hands. Galpin frames it as any training whose primary goal is to improve force production, muscle size, or a closely related physical quality such as posture, tissue resilience, and movement control.

That definition changes the conversation immediately. Bodyweight work counts. Gravity counts. A loaded squat counts. A controlled landing counts. What matters is whether the session improves the physical capacities that let you move well, absorb force, and produce force when life asks for it.

Galpin spends a large part of the conversation explaining that movement starts before muscle. First, the nervous system sends the signal. Then the muscle contracts. Then connective tissue transfers that force to bone. In practice, that means a good strength program can improve neural sequencing, coordination between opposing muscles, tendon function, and joint control long before you see visible muscle gain. It also explains why people often get stronger early in a lifting plan without adding much size.

That broader definition lines up with the health case for lifting that WHOOP has explored in Episode 187 of the WHOOP Podcast on strength training and health. When the goal is healthspan, the target is a body that can keep doing daily tasks, sport, and play with room to spare.

Galpin's definition is useful because it makes the training goal explicit:

"It's any sort of training in which the primary goal is to enhance strength or force production, or muscle size, or something equivalent."

What you should take away

• Strength training is defined by the adaptation you want, including force production, muscle size, movement skill, posture, and tissue resilience.
• Bodyweight training can qualify as strength training when it improves force production or a related physical capacity.
• Early strength gains often come from neural and connective tissue adaptations before large changes in muscle size appear.
• A health-focused strength plan should improve how you move, how you absorb force, and how much force you can produce.

Which strength qualities matter most for healthy aging and performance?

Once the definition is clear, the next question is which qualities deserve the most attention. Galpin lays them out on a continuum: skill, speed, power, strength, muscle size, and then muscular endurance.

That order matters because each quality overlaps with the next. Better skill can make you faster. More speed can raise power. More strength usually supports power and tends to travel with muscle gain. Muscle size has a clear relationship with strength, although Galpin is careful to point out that the relationship is not perfectly one to one. You can build strength without much hypertrophy, and you can add size without moving much better.

His explanation also helps answer the longevity question. A durable older adult needs more than basic cardiovascular fitness. Galpin points to decades of research that pushed this idea forward, including Stephen Blair's JAMA paper on physical fitness and all-cause mortality. He then makes the case that leg strength, grip strength, speed, and muscle quality all deserve attention when you care about how long and how well people live.

His example is practical. If climbing stairs feels like a near maximal effort, the problem is not only conditioning. Weak legs turn everyday movement into a hard task. Stronger legs lower the relative cost of living, from getting off a toilet to carrying groceries to moving quickly enough to catch yourself when you trip.

That same logic shows up in other WHOOP conversations about the difference between strength and stability, including Episode 41 of the WHOOP Podcast with Jordan Shallow. The useful takeaway is that healthy aging depends on several overlapping qualities, not a single test result.

Galpin boils the overlap down to a simple equation:

"Power is simply speed multiplied by strength."

What you should take away

• Skill, speed, power, strength, and muscle size overlap, so training one quality often influences the next one in the sequence.
• Leg strength can lower the relative effort of daily life and help protect mobility as you age.
• Speed still matters for longevity because quick force production helps with movement quality, balance, and reacting to the environment.
• Muscle size supports strength, and strength supports resilience in everyday tasks and sport.

How should you choose exercises, sets, reps, intensity, and order?

After the big picture comes the part most people want immediately: programming. Galpin says the key variables are choice, order, volume, intensity, frequency, progression, and rest. Change those well, and you change the adaptation.

His main programming rule is specificity. If you want speed, practice moving fast. If you want maximal strength, place more emphasis on load. If you want hypertrophy, place more emphasis on volume. That is why session order matters. Fast work and jump work belong early, when fatigue is low. Heavy compound lifts fit well in the middle. Higher volume accessory work can come later.

This is also where people often overcomplicate rep ranges. Galpin's answer is more useful than a rigid chart. For many people training for a blend of strength and muscle, a range of about 3 to 10 reps per set works well. The more important question is how close the set is to failure, and whether technique stays clean.

His practical standard is reps in reserve. If a given weight would let you do 10 hard reps, stop around 8. That keeps the set challenging while leaving a margin before form breaks down. For people who are newer to lifting, that is an accessible way to judge effort without formal one-rep max testing.

Progression is the other pillar. A program cannot stay identical forever. Galpin recommends progressing one or two variables at a time, often by adding a small amount of load each week, reducing rest, adding volume, or advancing exercise complexity. WHOOP members who want a second layer after this episode can use Episode 296 of the WHOOP Podcast on strength progression to think through how that gradual increase should unfold over time.

Galpin's reps in reserve example is the clearest single rule in the episode:

"If the maximum you could do in a set is 10 at that weight, maybe do 8."

What you should take away

• Exercise choice, order, volume, intensity, frequency, progression, and rest are the main variables that shape a strength adaptation.
• Specificity should guide programming, so fast work comes before fatigue, heavy work emphasizes load, and hypertrophy work emphasizes volume.
• A practical strength and muscle range for many people is about 3 to 10 reps per set, performed with clean technique.
• Reps in reserve is a useful way to judge effort when you do not know your one-rep max.

What does a simple two to three day strength routine look like?

With those variables in place, Galpin gives a simple template that many people can use right away. Two to three full-body sessions per week is enough to build a durable base for health, longevity, and general performance.

He starts with a brief speed or landing component after a warmup. That could mean a few box jumps, broad jumps, vertical jumps, or step-off landings. The point is to expose connective tissue and the nervous system to controlled force production and force absorption while you are still fresh.

From there, the workout shifts to large movement patterns. For the lower body, Galpin recommends a bilateral squat pattern, a bilateral hinge pattern, and a unilateral pattern such as a lunge, split squat, or step-up. For the upper body, he likes a mix of horizontal and vertical pushing and pulling. A goblet squat paired with an overhead press, or a hinge paired with a row, gives you a large amount of useful work without needing a long list of exercises.

Most people do not need body-part splits to get the benefits discussed in this episode. Full-body sessions cover more movement patterns, ask more of coordination, and fit real life better when training time is limited. Accessory work can still appear at the end if you want extra calf, arm, or trunk work.

This part of the conversation also explains why muscular work has been hard for wearables to capture through heart rate alone. WHOOP later addressed that gap in Episode 219 of the WHOOP Podcast on Strength Trainer, where the focus shifts from pure cardiovascular load to muscular load inside the session.

Galpin summarizes the weekly structure in one sentence:

"Two to three days a week, you're going to do mostly full body workouts."

What you should take away

• Two to three full-body lifting sessions per week can build a strong base for daily life, sport, and healthy aging.
• A balanced session can include jumps or landing drills first, then squat, hinge, unilateral lower-body work, and upper-body push and pull patterns.
• Full-body training fits general health goals better than body-part splits for many people with limited time.
• Large movement patterns usually deliver more useful return than a long list of isolation exercises.

How should you schedule sessions, manage soreness, and recover between lifts?

Once a routine exists, recovery becomes the limiter. Galpin's answer is that recovery depends on the adaptation you trained. Skill, speed, power, and many strength sessions can show up more often, while hard hypertrophy work usually needs 48 to 72 hours before you hit the same muscle hard again.

He is also clear that there is no magic spacing rule that applies to every session. Olympic lifters and powerlifters can squat frequently because they are managing volume, intensity, and technique with precision. A person chasing muscle soreness with high volume leg work will need more local recovery.

That distinction is why Galpin does not want people to judge training quality by soreness alone. His target is modest soreness that fades quickly. If you are so sore that three or four days of training disappear, the session cost too much.

Recovery habits in the episode follow a clear hierarchy. Sleep comes first. Galpin calls high-quality, consistent sleep the biggest foundation for recovery by far. He then points to precise nutrition and supplementation as a large part of how elite athletes stay ready. After that, thermal strategies such as sauna, cold water, or contrast work can help with soreness and overall fatigue.

This is where WHOOP metrics become useful. Sleep, Recovery, HRV trends, resting heart rate, and Strain can help you see whether a lifting block is creating adaptation or simply extending fatigue from session to session. The broader context for that load management question appears in Episode 158 of the WHOOP Podcast on the science of Strain.

Galpin gives a practical soreness target that many people can use immediately:

"You want to feel like maybe 3 out of 10 on the level of soreness, like the next day and the day after."

What you should take away

• Recovery needs depend on the quality you trained, and hypertrophy work usually needs more local recovery than speed or skill work.
• A useful soreness target is mild to moderate discomfort that does not wipe out the next several training days.
• Sleep is the main recovery foundation, followed by nutrition, and then optional tools such as sauna, cold water, and contrast work.
• WHOOP can help you see whether a lifting plan is building readiness or extending fatigue through Sleep, Recovery, Strain, HRV, and resting heart rate trends.

How should women approach strength training in perimenopause and menopause?

The core strength training principles stay the same for women, but the recovery picture can change a lot during perimenopause and menopause. Galpin says individual variation is large, and he avoids rigid rules unless symptoms and training response support them.

In practice, one issue stands out quickly in the women his team works with between about ages 40 and 60: nighttime temperature regulation. Disturbed temperature patterns can fragment sleep, and fragmented sleep can lower next-day training quality and recovery. For that reason, Galpin highlights temperature-controlled sleep setups as one of the fastest practical fixes he sees for this group.

That recommendation fits the overall logic of the episode. Better training depends on better recovery, and better recovery often begins with better sleep. WHOOP members can use Sleep and next-day Recovery trends to see whether a cooler sleep environment changes how rested they feel and how well they bounce back from lifting.

Galpin's most direct description of the problem is simple:

"One thing that's pretty ubiquitous is temperature regulation at night is so hard."

What you should take away

• Women in perimenopause and menopause often need the same training principles, with more attention paid to sleep quality and recovery constraints.
• Nighttime temperature regulation can become a major factor in sleep disruption during this stage of life.
• A cooler, more controlled sleep setup may improve recovery enough to support more consistent strength training.
• WHOOP can help members see whether sleep changes are improving next-day recovery after lifting.

The bottom line

• Strength training is best defined by the adaptation it develops, including force production, muscle size, movement skill, and connective tissue resilience.
• Healthy aging depends on more than muscle size, because skill, speed, power, strength, and enough muscle mass all support long-term function.
• A practical program can start with two to three full-body sessions per week built around squat, hinge, unilateral lower-body work, and upper-body push and pull patterns.
• Hard sets should usually stop with one or two good reps still available so technique stays sound while effort stays high.
• Progressive overload matters more than a perfect template, because a program must keep asking a little more from the body over time.
• Mild soreness that fades quickly is a workable target, while soreness that wipes out multiple training days is usually too costly.
• Sleep is the main recovery foundation for strength training, and other recovery tools sit on top of that base.
• Women in perimenopause and menopause may need extra attention on nighttime temperature regulation because sleep disruption can limit recovery from lifting.

Frequently asked questions about things discussed in this episode

How does WHOOP help you judge whether strength training is adding too much fatigue?

WHOOP helps you judge training fatigue by showing how Sleep, Recovery, Strain, HRV trends, and resting heart rate change across a lifting block. A run of low Recovery scores, rising resting heart rate, or falling sleep quality after repeated hard sessions can signal that your plan needs more recovery or less volume.

What does WHOOP do for strength workouts that heart rate alone can miss?

WHOOP can capture more of a strength session when you use Strength Trainer to log exercises, sets, reps, and load alongside heart rate data. That matters because muscular work often creates fatigue that a heart rate signal alone does not fully describe.

How does WHOOP help you schedule lifting across the week?

WHOOP helps schedule lifting by showing how well you recovered from the previous session before you train again. A strong Recovery score may support another hard session, while a low Recovery score can be a cue to reduce volume, shift the focus, or keep the work technical and lighter.

What does WHOOP show after a high-volume leg day?

WHOOP often shows the cost of a high-volume leg day through lower Recovery, higher Strain, changes in HRV trends, and disrupted Sleep if the session was especially demanding. Those patterns can help you decide whether soreness is staying in a useful range or turning into lingering fatigue.

How does WHOOP support people who are trying to improve sleep for better lifting recovery?

WHOOP supports sleep-focused recovery by showing whether bedtime habits and sleep environment changes are improving Sleep and next-day Recovery. That is especially useful when cooling the room, changing the sleep setup, or adjusting training timing to reduce nighttime disruption.

What does WHOOP do for people balancing strength work and general fitness goals?

WHOOP helps balance strength work with general fitness goals by putting lifting, conditioning, sleep, and recovery into the same week of data. Seeing those signals together makes it easier to keep building strength without letting fatigue crowd out the next session.

For people using WHOOP while building a lifting routine, the useful signal is whether each week leaves you stronger, well recovered, and ready to move fast again.
