Once you start working out on TRX, you'll find out that the types of workouts are endless, which is what attracted Jaime Pressly to the system. Jaime told Health: "I get bored easily, so my trainer, Mike Jones, introduced me to TRX . . . You use your body weight for resistance. We also do abs, plus 150 to 200 squats. We work the inner and outer thighs, the quads, the hamstrings. I enjoy feeling the burn and pushing myself."
