12-week recomposition · v1
Chest, core,
five down
Four sessions a week, with a slow deficit underneath it. The scale should move about a third of a pound a week — no faster.
Measurements — log every 4 weeks
Chest at the nipple line, arms down. Waist at the navel, relaxed, exhaled normally — not sucked in. Same time of day, first thing in the morning. For weight, log the seven-day average, never a single morning — day-to-day swings of two pounds mean nothing.
Your daily 100
Swap the movement, keep the streak. 100 band pull-aparts and a 60-second dead hang, every day. Same three minutes, same ritual — but it trains what opposes all the pressing instead of piling more onto it, and it costs nothing in recovery.
Why the push-ups come out. The load never changes, so the stimulus stopped years ago. And doing them daily means your chest never gets a recovery day — which is when muscle is actually built. Worse, they leave you pressing lighter on Monday, lowering the one number that does drive growth.
They’re still in the plan. Feet-elevated, close to failure, Saturday, with a log field. Tracked and progressive. That version works.
Your running stays. Easy 1–2 miles Wednesday and Sunday, hard intervals Thursday inside the leg session. Same three days you already run, placed so they don’t land on the pressing.
Training at 42
Tendons adapt slower than muscle. The risk isn’t heavy — it’s heavy arriving too fast. Cap any weight jump at about 5%, and never add load on the same lift two sessions running, even when the reps say you could.
Two deloads instead of one — weeks 5 and 9. Four weeks hard, one week easy. This cadence is the main structural concession to your age, and it’s why the peak block should feel strong rather than grinding.
The peak block stays at six-plus reps. Low-rep heavy work buys little extra size and carries most of the joint risk. You’re training for a chest, not a one-rep max.
Sleep is the real limiter, more than any programming detail. Six hours a night in a deficit at 42 will flatten this plan no matter how well it’s written — recovery is when the adaptation actually happens.
Eating for this
Small deficit, not a diet. Four pounds over twelve weeks is a third of a pound a week — roughly 200 to 300 calories a day. That’s a slice of bread and a pour of oil, not a regimen. Anything faster and you’re paying for the scale with the chest.
Protein goes up, not down. Roughly 1 g per pound of bodyweight now, higher than you’d need at maintenance. In a deficit this is the single thing standing between you and losing muscle alongside the fat.
The deficit comes from food, not more cardio. Don’t add runs. Extra conditioning stacked on a deficit digs a recovery hole, and the first thing that falls in is Monday’s pressing.
The logbook is the dashboard. If your primary lifts stall two weeks running, the deficit is too steep — eat more. Strength holding steady while the scale drifts down is the whole target.
Faster is not better. More than three quarters of a pound in a week and some of it is muscle. Weigh in daily if you want, but only ever read the seven-day average.
Where this ends — week 12
- Bodyweight −3 to −5 lb, arrived at gradually. Roughly 2 lb by week 4, 3.5 by week 8, the rest slowly.
- Waist −1 to −1.5 inches. The deficit buys you more here than it does anywhere else.
- Chest flat to +0.5 inch. Holding chest measurement at a lower bodyweight is a real win — don’t read flat as failure.
- Incline dumbbell press: at least one dumbbell size up from week 1 at the same reps. Two if the deficit stays gentle.
- Dips: 15 clean bodyweight reps, or bodyweight +25 lb for 6.
- Ab wheel: 10 full rollouts from the knees, nose to floor, back flat.
- Photos at week 0, 6, and 12 — same light, same spot, same time of day.
Weeks 1–3 will feel like nothing is happening. That’s normal and it isn’t information. The logbook is where progress shows up first — if the numbers in it are climbing while the seven-day weight average drifts down, the plan is working regardless of what the mirror says in week 3.
