How long should I rest between sets for hypertrophy vs. strength?

For maximal strength (1-5 reps), rest 3 to 5 minutes to fully regenerate muscle phosphocreatine (PCr) stores. For muscle hypertrophy (6-12 reps), rest 60 to 120 seconds to balance metabolic stress and high mechanical tension.

What is the classic Tabata protocol?

The classic Tabata protocol developed by Dr. Izumi Tabata consists of 8 rounds of 20 seconds of all-out maximum intensity exercise followed by 10 seconds of rest, completing in 4 minutes.
