1. back hurts when I do abs 2. 30DS vs turbo jam

1. Every time I try to work my abs my back ends up being really sore the next day. I don't know if it's because my abs are so weak or what. What kind of ab workouts can I do that won't hurt my back?

2. I have been alternating between the 30 day shred and the turbo jam cardio party 1. the exercise database says that I burn more calories doing the turbo jam than I do the 30 day shred. I feel like I'm working twice as hard when I do the 30ds than when I do the turbo jam. Any insight?

when you lay down to do crunches tilt your pelvis and relax your back (breathe into) before you even start & when you're sitting up your neck should be open and facing the ceiling.
Maybe you're already doing that I dunno... just my two cents

1. You're probably doing them wrong. I do crunches regularly with or without a ball and never have an issues with my back.
2. Get an HRM

Maybe I should get a ball...... I'm really bad at focusing on keeping my abs tight.

What's an HRM?

HRM is a Heart Rate Monitor. I have one that is like a watch that I wear on my wrist, but I would strongly suggest getting one with a chest strap. You can purchase them at any sports store, or even Walmart or Target. The one I have is the Sportline brand, but it does not have a chest strap, I question it's accuracy from time to time, but it gives me a general idea.

My answer to number 2...TJ is longer. It's about 45 minutes while 30DS is 27 minutes. There's a lot of cardio in TJ, while 30DS is not all cardio.
