Accepted answer
Seven sessions a week against 1,400 kcal a day — 9800 kcal for the week — and at that intake the binding constraint is almost never the session count. Protein at 4 kcal per gram is the reason: 100 g a day is 400 kcal, 29 per cent of 1,400, and 2800 kcal of the 9800 for the week spoken for before anything else is eaten. 7 sessions also has to be recovered from on 1,400 kcal, and recovery is the first thing an energy deficit takes. Load matters more than frequency here: the stimulus that preserves mass is mechanical tension, so keep the weight and cut the volume rather than the reverse. None of this is medical or dietary advice.
The relevant constraint is recovery: a deficit reduces recovery capacity, so the sensible adjustment is volume down slightly and intensity held.
Load is the retention signal. Reducing weight and adding repetitions preserves the workout and weakens the stimulus, which is exactly backwards for this objective.
Protein target arithmetic
| Body mass | 1.2 g/kg | 1.6 g/kg | 2.0 g/kg | Per meal at 1.6 (÷3) |
|---|
| 62 kg | 74 g | 99 g | 124 g | 33 g |
| 74 kg | 89 g | 118 g | 148 g | 39 g |
| 88 kg | 106 g | 141 g | 176 g | 47 g |
| 103 kg | 124 g | 165 g | 206 g | 55 g |
| 124 kg | 149 g | 198 g | 248 g | 66 g |
At roughly 4 kcal per gram, 141 g of protein is about 564 kcal — a substantial fraction of a 900 kcal budget, which is the real constraint.
The underlying point is that two sessions per muscle group per week outperforms one at matched volume in most of the published comparisons, mainly through better session quality.
Frequency studies generally favour twice-weekly over once-weekly per muscle group at equated volume.
Nothing here is medical advice.
Compound movements first, because recovery is the scarce resource.
