The short version
- Train major muscle groups at least 2 days a week with challenging sets.
- Progress gradually: more reps, sets or weight over time.
- Eat enough protein and total food, and sleep 7+ hours.
Building muscle is simple, not easy. It comes down to four things done consistently for months.
1. Train
Do full-body strength sessions 2 to 3 times a week: a squat or lunge, a hinge, a push, a pull and a carry. 2 to 3 sets of 8 to 12 reps, taken close to (not always to) failure.
2. Progress
Add reps or weight when sets get easy. See progressive overload.
3. Eat
The ISSN position stand suggests 1.4 to 2.0 g of protein per kg of body weight per day for most exercising people, higher than the general RDA of 0.8 g/kg. Use our protein calculator.
4. Sleep and recover
Most adults need 7 to 9 hours. Muscle is built between sessions.
Age is not a barrier: the guidelines recommend muscle-strengthening work for adults of every age.
Do this today
Schedule two strength sessions this week in your calendar, and use the protein calculator to get your target.
Questions people ask
How long does it take to build muscle?
Beginners often notice strength gains within weeks; visible size changes usually take a few months of consistent training.
Can I build muscle at home?
Yes, with bodyweight, bands or dumbbells, as long as sets are challenging and progress over time.
Can I build muscle after 50 or 60?
Yes. Guidelines recommend strength training for older adults too. Ask a clinician if you have health conditions.
