The best rep ranges for building strength after 40

Why rep ranges matter more now

In your 20s you could do almost anything for reps and recover fine. Squat heavy triples one day, bang out 20 push-ups the next, no big deal. After 40 your joints and tendons take longer to bounce back than your muscles do, so the total pounding you put through them starts to matter as much as the effort.

This doesn't mean going soft. It means picking rep ranges that build strength without turning every session into a recovery debt you're still paying off on Thursday.

The sweet spot for most lifts

For big lifts like squats, presses, and rows, 5 to 10 reps per set is the workhorse range after 40. Heavy enough to build real strength, light enough that your form doesn't fall apart on the last rep.

Save the 1 to 3 rep max-effort stuff for when you're fully recovered, warmed up properly, and not testing it on a random Tuesday after a bad night's sleep. It's not banned, it's just not where you should live week to week.

• Goblet squat or bodyweight squat: 6 to 10 reps
• Incline dumbbell press or push-up: 6 to 12 reps
• One-arm dumbbell row or chin-up: 5 to 8 reps
• Romanian deadlift: 6 to 10 reps

Higher reps still earn their keep

Higher rep work, think 12 to 20, isn't wasted time. It's good for joints that need blood flow more than heavy load, and it's a smart way to build muscle without hammering a cranky knee or shoulder.

I use higher reps on stuff like lateral raises, bicep curls, and calf raises. Nobody needs a 5-rep max lateral raise. Save the joint-friendly high-rep sets for the smaller accessory lifts and keep the heavy lifting for the big compound moves.

• Dumbbell Lateral Raise: 12 to 15 reps
• Standing Calf Raise: 15 to 20 reps
• Standing Dumbbell Curl: 10 to 15 reps
• Bicycle Crunch: 15 to 20 reps

Leave a couple reps in the tank

This is the bit that changes the most after 40. You don't need to grind every set to failure to get stronger. Stopping one or two reps short of your max keeps your joints happier and your next session isn't wrecked before it starts.

A good gut check: if your form is getting sloppy or your breathing sounds like you're auditioning for a horror movie, that's your last rep, not two reps ago. Strength built on ugly reps doesn't transfer well anyway.

Putting it together in a week

You don't need five different rep ranges running at once. Pick your main lifts, keep them in the 5 to 10 range twice a week, and let your accessory work live higher, 12 to 20, once or twice a week. That's plenty of variety without overcomplicating things.

If you want a structure that's already laid out this way, the 3-Day Dad Strength Split does exactly this: heavy-ish compound lifts paired with higher-rep accessory work, built for guys training around a job and a family, not around a competition.
