Is resistance training three times a week enough at 900 kcal a day?

Asked 15 Aug 2024Modified 21 months agoViewed 39k times

Stated plainly: three · 900 kcal.

I am trying to build something sustainable rather than something thorough that I will abandon.

I have already decided the broad direction; this is about the specifics.

What should I decide now, and what should I defer?

Three sessions a week against 900 kcal a day — 6300 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, 44 per cent of 900, and 2800 kcal of the 6300 for the week spoken for before anything else is eaten. Two to three hard sessions is enough stimulus to defend lean mass; the literature stops improving much past that even at maintenance intake. 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.

Mechanically, two sessions per muscle group per week outperforms one at matched volume in most of the published comparisons, mainly through better session quality.

Training-to-failure comparisons show similar hypertrophy with substantially greater fatigue when sets are taken to failure rather than near it.

Research-use compounds are not approved for human use and are not a substitute for a training stimulus.

In a deficit, maintaining performance is progression. Reframe it and stop being discouraged.

Answering this needs to know training history, because a beginner in a deficit can still gain and an advanced trainee cannot.

Protein timing matters far less than protein total, but a serving within a few hours either side of training is a free optimisation.

More usefully, session performance is the practical readiness signal. Two consecutive sessions where loads drop at matched effort usually means recovery, sleep or intake rather than programming.

Frequency studies generally favour twice-weekly over once-weekly per muscle group at equated volume.

Compound movements first, because recovery is the scarce resource.

This is one of the tags where the evidence is unusually consistent and the arguments are unusually heated.

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.

Concretely, appetite suppression reduces training fuel as well as protein, and low-carbohydrate sessions feel much worse than they perform. Judge by load, not by feel.

Load-matched comparisons show that maintaining intensity preserves strength and lean mass in a deficit better than reducing load and increasing repetitions.

One to three reps in reserve. Failure costs more than it returns here.

Progression in a deficit is measured in maintained performance rather than added load, and reframing it that way prevents a lot of discouragement.

Beginners retain the ability to gain muscle in a moderate deficit for several months; trained individuals should expect maintenance and be satisfied with it.

The caveat is that programme design is individual, and anyone with joint, cardiac or metabolic constraints needs a professional rather than a forum.

Ten sets per muscle group per week, twice weekly, loads held. That is most of it.

Compound movements give the most stimulus per unit of recovery, which matters more when recovery is the limiting resource.

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.

Volume dose-response meta-analyses place most of the hypertrophy benefit below about ten to twenty weekly sets per muscle group, with diminishing returns above.

Nothing here is medical advice.

Consistency beats optimisation by a margin nobody wants to hear.
