"I'm a firm believer in trying to make something that might not be considered fun by a lot of people ..." — Gunnar Peterson

You don't have to be built like Karl Malone to be strong. There are thinner guys who are really strong. Kevin Durant, who I used to work with, has real strength to his body.

The Gunnar Challenge offers new workouts every day, a meal plan and daily 'verbal vitamins,' which are a motivational video or workout tip. The thing that really makes the program work is the forum, where Challengers can communicate with each other and with me.

I don t have a scale; I'm not big on measurements. Until a person looks in the mirror and is happy with themselves, you have not reached your fitness goals.
