The weighted sit-up also known as the kettlebell sit-up is a tough exercise but it’s totally worth it if you want a nice set of abs.
HOW TO DO IT: For this exercise you need a kettlebell or another easy to grip object. You can hold a gallon jug of water or milk, or something round and heavy like a bowling ball. Grab the kettlebell with both hands and get into a sit-up position. Now curl your shoulders and head off of the ground and slowly move the kettlebell down towards your legs.
Keep sitting up until you are at the top of the sit-up position. Try to keep the kettlebell as close to your chest as possible while you sit up. If you reach the kettlebell too far forwards the weight will help you sit all the way up instead of making your abs do all of the work.
Pull the kettlebell back towards your chest and slowly roll down the mat with your back. Keep your feet flat on the ground as you lower yourself. Keep pulling the kettlebell back towards your chest as you slowly roll all the way back to the ground.
Adding a Kettlebell into this conventional exercise will build added strength and is guarenteed to get your abs firing.
