Exercise tips and tricks

Choose the Right Ball Size: Make sure the stability ball is the correct size for your height. Your knees should be at a right angle when you sit on the ball.
Engage Your Core: Keep your core muscles engaged throughout the entire exercise to maintain stability and maximize effectiveness.
Control Your Movements: Perform each move slowly and with control to maximize muscle engagement and reduce the risk of injury.
Breathe Properly: Exhale while crunching up and extending your legs, and inhale while returning to the starting position. Proper breathing will help you maintain rhythm and energy.
Stabilize with Your Hands: If you're new to this exercise, keep your hands on the floor for extra support until you build more core strength.
Avoid Overextending: Don't overextend your legs, as this could put unnecessary strain on your lower back. Only extend your legs as far as you can while maintaining proper form.
Keep Your Back Flat: Ensure that your lower back remains flat against the stability ball as you perform the crunch to engage your abdominal muscles fully.
Focus on Quality, Not Quantity: It's better to do fewer reps with proper form than more reps with poor form. Focus on each movement to get the most out of your workout.
Consistent Tension: Maintain tension in both your legs and abs throughout the exercise to improve muscle activation and endurance.
Modify as Needed: If the straight-leg extension is too challenging, try bending your knees slightly to make the exercise easier.
