1. Lie down on the mat, keep your knees bent, your back and feet flat, and your hands supporting your head.
2. Lift your shoulders, squeeze your abdominal muscles and hold for 1 to 2 seconds.
3. Slowly return to the starting position and repeat until set is complete.
PROPER FORM AND BREATHING PATTERN
When doing crunches keep your head in a neutral position, with your eyes on the ceiling and the chin off your chest. Breathe out as you crunch, maintain your core muscles tight and engaged and keep the elbows out.
Crunches target the abdominal muscles and adding them to your workout routine helps to tone and strengthen your core, improves your posture, trims down your waist and increases your balance and stability.
SETS AND REPS
Start with 2 or 3 sets of 15 to 20 repetitions. You can increase the challenge by doing modified versions of crunches, like roll ups and sit ups. Alternate exercises frequently so that your muscles don’t get accustomed to the same moves.
