Q: My question concerns the combination of your Maximum Strength program and HIIT workouts. Comments I have read by you indicate that HIIT training is detrimental to progress in your program. Could you explain why? Thanks for all that you do.

A: Give this article a read; it should answer your questions:

Of course, some things change if you are a guy who is more focused on getting lean, maintaining/improving cardiovascular fitness, or conditioning for a particular sport that warrants a lot of interval training. It’s the give and take between maximal strength and performance in some other discipline.

There are a lot of elite strength and power athletes who couldn’t run a mile in under 12 minutes – or even finish a mile at all! These are the folks who either a) have to keep body fat levels in check with diet, lifting, and very low intensity supplemental activity or b) not worry about body fat levels much at all, as strength and power are the name of the game.
