Body Recomposition Guide
Lose Fat and Build Muscle at the Same Time
For years the rule was "you can't do both at once." That advice was built for advanced bodybuilders, not for you. With the right training stimulus, the right nutrition and real recovery, body recomposition is exactly how most people get leaner and stronger at the same time. Here's how to do it without juggling two separate plans.
The four levers of recomp
- Small calorie deficit - enough to lose fat, not so much you lose muscle.
- High protein - around 1.6–2.2g per kg of bodyweight to protect and build muscle.
- Progressive strength training - heavier or more reps each week so muscle has a reason to grow.
- Real recovery - sleep, deloads and rest days, not just more workouts.
Get those four right at the same time and your body composition shifts even when the scale barely moves. Get one wrong and you stall.
Why most "lose fat and build muscle" plans fail
- Generic plans pick one goal and ignore the other.
- Calorie targets are too aggressive, so strength tanks and so does muscle.
- Training is cardio-heavy, with no real progressive overload.
- Nothing adjusts when a week goes badly, so progress stalls and motivation dies.
How A90's dual-goal system handles it
Inside the A90 app you set a primary goal and a secondary goal. Lose Fat + Build Muscle is the most popular pairing for a reason - it's what most people actually want. A90 weights your training, calories and protein toward your primary outcome while protecting the secondary one, and the plan adapts every week based on real progress and how the week actually went.
Missed a session? Swap it to another day. Busy week? The plan reshuffles rest days around you. The goal is consistent progress on both fronts, not a perfect streak you have to defend.

FAQ
Can you lose fat and build muscle at the same time?
Yes. It's called body recomposition. It needs a small calorie deficit, high protein, progressive strength training and proper recovery. A90 is built around this dual-goal approach so the plan does the balancing for you.
How long does body recomposition take?
Visible change usually takes 8 to 12 weeks of consistent training and nutrition. That's why A90 phases run 30, 60 or 90 days: a 90 day block is long enough to see real recomp, and when it ends you start the next phase rather than stopping.
Do I need to bulk and cut separately?
Not unless you're an advanced lifter or competing. For most people, a personalised plan with a small deficit and the right training stimulus produces leaner, stronger results without the bulk-cut cycle.
How does A90 handle two goals at once?
You set a primary goal (e.g. Lose Fat) and a secondary goal (e.g. Build Muscle). A90 weights your training, calories and protein to push the primary outcome while protecting the secondary one, then adjusts every week based on real progress.
