8 Minute Abs workout

I'm not sure where I stole this from but I have used it and find that it is just a great workout for the abs to gain that essential core strength.

Do 2 sets of the 8 different exercises for 30 seconds each...with absolutely NO rest in-between the exercises. 8 straight minutes of work. You'll notice a big change if you stick with it. It's really hard to explain some of these through words and if your not sure you can problably ask at the Gym or search on the net but here goes...
1. Straight Leg Lifts (lying on your back...legs never touch the ground, raise your legs to a 45 degree angle)
2. Scissor Kicks (lying on your back, legs straight, always off the ground)
3. Leg Ups (start with body fully straight on the floor, bring your knees to your chest, and then raise your legs to a 90 degree position)
4. Raised Toe Touches (lying on your back...legs raised at 90 degrees, raise your upper body off the floor, and touch your hand to opposite foot
5. Heel touches (lying on your back, shoulders off the ground, knees bent, feet on the floor, move side to side, touching your heels)
6. Crunches
7. Bicycles (touching knee to opposite elbow each time)
8. Kick outs
Do these exercises, in a row, 30 seconds each, then repeat the cycle.
Oh Yea !!!!
