Scope: General fitness education for adults 18+. It is not rehabilitation or medical nutrition therapy. Use stable equipment and stop for concerning symptoms.

Four rules that beat random workouts

  1. Train every major movement repeatedly. Squat/lunge, hinge, push, pull and brace.
  2. Use multiple challenging sets. A 2023 network meta-analysis found all resistance-training prescriptions outperformed no exercise for hypertrophy, with multiset programs ranking well.
  3. Progress gradually. Add clean repetitions, load, range of motion or a harder variation—one variable at a time.
  4. Recover. Muscle gain requires repeated training, sufficient food and sleep; more fatigue is not automatically more growth.

Three non-consecutive full-body days

Workout A

Squat · horizontal push · row

Goblet/backpack squat 3 × 8–12 · push-up or dumbbell press 3 × 6–12 · one-arm row 3 × 8–15/side · Romanian deadlift 2 × 8–12 · plank 2–3 sets.

Workout B

Split squat · overhead push · pull

Supported split squat 3 × 8–12/side · overhead press or pike push-up 3 × 6–12 · band pulldown or row 3 × 8–15 · hip thrust 2 × 10–15 · side plank 2 sets/side.

Schedule

Week 1: A / B / A · Week 2: B / A / B

Rest roughly 1–3 minutes between demanding sets. Most sets should end with about 1–3 technically sound repetitions still possible.

The double-progression rule

Choose a repetition range, such as 8–12. When every set reaches 12 with stable technique and the planned effort, add a small amount of resistance and return near 8. If load cannot increase, slow the lowering phase, increase range of motion or use a harder stable variation.

Record the exercise, load or variation, sets and repetitions. If performance declines across several sessions, reduce one set per exercise for a week before adding more work.

Food-first support for muscle gain

Include a meaningful protein source at 3–4 eating occasions: eggs, dairy, fish, poultry, lean meat, beans, lentils, tofu or soy. A major meta-analysis found protein supplementation modestly enhanced resistance-training gains, with little additional fat-free-mass benefit beyond total intake around 1.6 g/kg/day in healthy adults. Supplements are optional; food can do the job.

  • Breakfast: eggs + oats + fruit, or Greek-style yogurt + oats.
  • Lunch: rice/potato + beans and/or animal/soy protein + vegetables.
  • After training: use the next normal protein-containing meal; there is no need to panic about a narrow “window”.
  • If body weight and gym performance never rise: add one repeatable food serving, then reassess after two weeks.

If you have kidney disease, a prescribed diet, allergies or another clinical condition, discuss nutrition changes with an appropriate clinician.
