Accepted answer
Four sessions a week against 1,200 kcal a day — 8400 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, 33 per cent of 1,200, and 2800 kcal of the 8400 for the week spoken for before anything else is eaten. 4 sessions also has to be recovered from on 1,200 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.
Answer first: the objective in a deficit is retention, not growth, and retention needs load maintenance and adequate volume rather than progression.
Around ten hard sets per muscle group per week is the region where most of the retention benefit is realised; more produces diminishing returns and, in a deficit, a recovery cost.
More usefully, training close to failure — one to three repetitions in reserve — is sufficient. Training to failure adds fatigue disproportionately to stimulus and is a poor trade when recovery is constrained.
Training-to-failure comparisons show similar hypertrophy with substantially greater fatigue when sets are taken to failure rather than near it.
Published averages conceal wide individual response variation, particularly in older trainees.
One to three reps in reserve. Failure costs more than it returns here.
Thank you — reframing progression as maintained performance was genuinely useful. – Dr_Bram_Verhoeven 3 months ago add a comment
