I like that they're are already planned out, not to difficult to do but still get an amazing workout. The trainers are fun and motivating. I especially love how Coach David Fajardo will help you understand more in depth why you should use a heavier weight here or a lighter one here. How if you can't go back to your base pace from an all out then your all out is too fast, etc. Helps me feel like I'm being more effective.
The fun and unique workouts. Every day is something new. I don't have to think about what I will do when I get to the gym. I show up and get in zone 4 and stay there as long as I can. I don't have to get a subscription to Oily Men's magazine and design my own workouts. I'm getting fit and strong without the testosterone based meat head weightlifting scene.
