Crunches are one of the most widely known forms of exercise. When done correctly it strengthens your core, obliques, upper and lower abdominal muscles. This in turn helps to support your back and any physical daily activity as it all starts with the core.
This week’s challenge is not for the faint of heart. Remember to PUSH yourself. If you don’t feel it, you aren’t doing it right.
Advanced: 25 crunches – Legs in the air at 45 degrees. Keep shoulders off the ground.
Intermediate: 15 crunches – Bent knee. Keep shoulders off the ground.
Beginners: 5 crunches – Bent knee. Keep shoulders off the ground.
Perform 3 sets of these with a 30 second rest in between. By the end of the week you will be on your way to stellar abs and a stronger core.
Feel free to change it up with the following suggestions:
- Crunches on a bosu ball
- Crunches on a balance ball
- Leg lifts to work the lower abs
- Pass a balance ball between hands and ankles for an extra workout
YOU CAN DO IT!
