High Crunches
Lie on your back with your knees bent and feet flat on the floor. Extend your arms straight up towards the ceiling. This is the starting position.
Exhale and lift your shoulder blades off the floor, reaching your arms straight upward as if trying to touch the ceiling. Focus on using your abdominal muscles rather than momentum.
Hold the contracted position for a second or two at the top of the crunch.
Inhale and slowly return to the starting position, maintaining control throughout the movement. Don't let your back or neck arch as you lower down.
Repeat for the desired number of reps. Start with 10-15 reps and work your way up.
For more challenge, you can hold a weight plate or dumbbell against your chest. Or extend your arms straight past your head rather than pointing up.
