4-day Upper/Lower home (no equipment) plan to build muscle

Moderate weight, 6–12 reps. Rest about 2 minutes on main lifts and 90 seconds on the rest. Finish most sets 1–2 reps short of failure, and log RPE so targets adapt.

How to progress

When you hit every rep on every set, add weight next time: 2.5 kg on upper-body lifts, 5 kg on squats and deadlifts. Miss reps, keep the weight and try again. MyoStats does this for you: it shows the target for each exercise before you start, and suggests a lighter week when a lift stalls.

Questions

Is a 4-day upper/lower split good to build muscle?

Yes, if you can recover from it and stay consistent. Moderate weight, 6–12 reps. Rest about 2 minutes on main lifts and 90 seconds on the rest.

How long should I run this program?

Run it for 8 to 12 weeks while you keep adding weight or reps. When progress stalls on a lift for two or three sessions, take a lighter week, then carry on. MyoStats spots the stall for you.

What weights should I use?

Pick a weight you can lift for the target reps with one or two reps left in the tank. After you log a session, MyoStats suggests the next weight or rep target for every exercise.

Can I do this at home?

Yes: no equipment needed. A pull-up bar or a sturdy table for rows helps.
