Frequently Asked Questions

How does sleep quality impact muscle protein synthesis?

Deep sleep (N3 stage) is when the body releases the majority of growth hormone. Poor sleep quality suppresses this release, directly hindering the repair and hypertrophy of muscle fibers damaged during training.

Should I train if I had a poor night of sleep?

If sleep was significantly disrupted, prioritize a deload or active recovery session. Training at high intensity while sleep-deprived increases systemic inflammation and injury risk without providing the necessary stimulus for growth.
