How long should a leg workout be?

For leg workouts, Andrew Huberman recommends a duration of about 50 to 60 minutes of intensive training, following a 10-minute warm-up. He emphasizes not exceeding roughly one hour because prolonged workouts can increase cortisol levels, which may impede recovery. This is particularly important as it aligns with his general practice for ensuring optimal recovery and avoiding overexertion which he found personally leads to diminished returns from workout to workout 1 2.

For a more detailed regimen, he sometimes follows a rotated scheme based on the type of resistance training and muscle group focus, which involves varying the repetition ranges and number of sets based on the training phase 3. He mentions that longer rest intervals might be needed for heavy leg work 3.
