Recovery & frequency
The questions about recovery and frequency, answered plainly.
Frequently asked
How often should I train HIT?
Less than you think. Two to three full-body sessions per week is a common start; many reduce as intensity rises. Recovery decides, not a calendar.
How do I know if I've recovered?
Performance is the honest signal. If your working-set reps and weight are climbing, you've recovered. If they stall or regress, you need more rest.
Can I train if I'm still sore?
Soreness is a weak signal; performance is the real marker. If performance is up, you can train; if it's down, wait regardless of soreness.
Why does HIT prescribe rest?
Because intensity is fixed at 'to failure', frequency is the only lever. Adaptation happens between sessions, so recovery is the limiting factor.
Failure Point is a training logbook, not medical advice. Training to failure carries injury risk.
Consult a physician before starting any intense training program.
