Crunches are a great way to strengthen your core and tone your abs.
To do a basic crunch, lie on your back with your knees bent and your hands behind your head.
For a reverse crunch, start in the same position as a basic crunch but lift your legs off the ground and bring your knees towards your chest.
To do a bicycle crunch, lie on your back with your hands behind your head and your legs lifted off the ground.
Make sure to keep your core engaged throughout each exercise and avoid pulling on your neck.
Incorporate these three crunch variations into your workout routine for a stronger core and toned abs.
Remember to also maintain a healthy diet and engage in regular cardiovascular exercise for optimal results.
