One of my friends just gave me this workout yesterday. You will feel the burn.
Here’s it is:
- 10 Crunches
- 10 Side Crunches (left)
- 10 Side Crunches (right)
- 10 Bicycles
- 10 Reverse Crunches
- 10 Vertical Crunches (legs straight up, arms crossed)
- 10 Toe Touch Crunches (legs straight up, arms extended)
- 10 Crunches (with legs flat on ground & criss-crossed)
Then you would do 10 push-ups or another short exercise in between and do the routine again backwards (10 crunches w/legs flat to 10 toe touch crunches to ten vertical crunches… etc.)
If this workout becomes too easy, change every 10 reps to 20 reps. When that becomes easy I would suggest doing the whole workout twice, and then continuing to increase the reps as you see fit.
