212 pieces on the questions people actually search — how many calories, how much protein, how big a deficit, what a set at RIR 2 means, how the 1RM estimate works, how many sets a week — with every number derived from the formulas the apps use or cited to a source you can open. Training and nutrition education only; never medical advice.

Do cluster sets build more muscle?
No: a meta-analysis of 29 studies found cluster sets and traditional sets built muscle equally. A 2025 effort-matched trial agreed. What cluster sets do change.
Human trial dataTraining methods7 minDo ice baths kill your gains?
Not kill, but trim: cold water after every lifting session cut strength gains slightly (−0.23 across 10 studies) and muscle growth by a similar amount.
Human trial dataTraining methods8 minDo slow reps build more muscle?
Mostly no. A 2025 meta-analysis of 14 studies found slow reps (about 3.5 s) and fast reps (about 1 s) grew muscle about equally, with a trivial gap.
Human trial dataTraining methods6 minDo women build muscle as fast as men?
Relative to where they start, yes. On the same program, women and men grew muscle by a similar percentage: a gap of 0.69% in a 2025 analysis of 29 studies.
Human trial dataTraining methods8 minDo you have to train to failure to build muscle?
No. In an 8-week trial, a leg trained 1–3 reps short of failure grew as much as the leg taken to failure. What the studies show, and what stopping short costs.
Human trial dataTraining methods8 minDoes drinking alcohol after training kill your gains?
Not outright, but a heavy dose after training cut the muscle-building rate by 24% even with protein and 37% without it in one trial. What other studies show.
Human trial dataTraining methods7 minDoes blood flow restriction training work?
Yes for muscle size: in 53 studies, light lifting with a cuff grew muscle about as much as heavy lifting. Heavy lifting still built more strength overall.
Human trial dataTraining methods8 minDoes cardio kill your gains?
Mostly no. Across 43 studies, adding cardio to lifting did not reduce muscle growth or max strength; explosive strength dipped slightly (SMD −0.28). Details.
Human trial dataTraining methods7 minDoes eccentric training build more muscle?
Maybe slightly. In 15 trials, lowering-only training grew muscle 10.0% vs 6.8% for lifting-only, but the gap was not statistically clear. Both halves work.
Human trial dataTraining methods8 minDoes exercise help you sleep better?
Modestly, on average. A review of 66 studies found small gains in sleep time and a moderate one in self-rated sleep quality with regular exercise, lifting too.
Human trial dataTraining methods7 minDoes exercise order matter?
For strength, yes: lifts done first gained more in an 11-study meta-analysis. For muscle growth, barely: the order effect was 0.03, essentially zero.
Human trial dataTraining methods7 minDoes foam rolling work?
A little: 21 studies found a small short-term flexibility gain from rolling before exercise and slightly less soreness after, but no gain in strength.
