About this workout
Building muscle while losing fat, true body recomposition, is possible, and it comes down to two things: training hard enough to build and keep muscle, and eating enough protein at roughly maintenance calories so your body reshapes itself. This 12 week, 4 day upper/lower plan provides the training half. You lift with real intensity to signal your body to hold and add muscle, while your nutrition slowly strips fat. Progress on the scale is slow because you are trading fat for muscle, but the mirror tells the real story.
Who This Program Is For
- You want to build muscle and lose fat at the same time.
- You can train four days a week with intent.
- You have access to a full gym.
- You already train and are ready to be patient with a slow-moving scale.
Who this is NOT for: total beginners, who recompose almost automatically on a simpler plan, and anyone who needs fast scale weight loss, where a straightforward deficit is better. Recomp rewards patience.
What You'll Need
- A full gym with barbells, dumbbells, cables and a pull-up bar.
- A way to track protein and calories; recomp lives and dies by nutrition.
- A log, and the discipline to judge progress by the mirror and strength, not just the scale.
The Program
Four days: two upper, two lower. A good layout is Monday upper, Tuesday lower, Thursday upper, Friday lower. Train with real intensity, leaving a rep or two in reserve, because hard training is the signal that tells your body to keep muscle while you lose fat.

How to Progress
Twelve weeks of holding and adding muscle while the fat comes off, with a deload to keep training quality high.
Weeks 1 to 4. Set your working weights and train hard while you dial in eating at maintenance with high protein. Aim to keep your strength up; that means you are keeping muscle.
Weeks 5 to 8. Keep pushing to hold or slightly increase your lifts. If strength is climbing while the mirror leans out, recomp is working.
Week 8 (deload). Take a lighter week. Recovery keeps training quality high, which is what protects your muscle in a recomp.
Weeks 9 to 12. Keep training hard and let nutrition do the fat loss. By week 12 you should look leaner and more muscular even if the scale has barely moved.
Warm-Up and Recovery Notes
Warm up with light cardio, mobility and ramp-up sets on your first lift. Training hard in a recomp needs a good warm-up to keep quality high.
Recovery can be a little harder near maintenance calories, so protect your sleep and keep any extra cardio moderate. The priority is training hard enough to keep every ounce of muscle.
Nutrition and Supplementation
Recomp is a nutrition game. Eat at or just below maintenance calories with high protein, around one gram per pound of bodyweight, to build and hold muscle while slowly losing fat. Keep protein high on every meal and build the rest of your plate around whole foods and vegetables.
Support: protein powder to hit high protein easily, creatine monohydrate at 5 grams a day to preserve strength and muscle, and a daily multivitamin. Protein is the single most important nutrient for recomposition.
FAQ
Can you really build muscle and lose fat at once? Yes, especially if you are not an advanced lifter and you keep protein high and training hard. It is slower than doing one at a time, but it works and the results are excellent.
Why is the scale not moving? Because you are losing fat and gaining muscle at the same time, which can keep your weight nearly steady. Judge progress by the mirror, your measurements and your strength, not the scale alone.
How long until I see results? Recomp is gradual. Give it the full 12 weeks and track photos and strength; the changes are clear over time even when week to week is subtle.
