We do not need any special equipment to work on abs. Instead, we can use the mentioned below equipment which are commonly available in gyms that can help in adding little variety to same old crunches.
An Exercise ball is one of the equipment, which we can use on our own. Ball Crunch is the most effective exercise for abs. We can use it while watching TV or while working on the computer for better posture. We have to choose the right size according to height.
BOSU (Both Sides Up) Balance Trainer:
It has a flexible dome and a flat platform underneath that allows standing, jumping, squatting and bouncing. BOSU is great equipment as abs and back are involved in balance and stabilization.
BOSU Ballast Ball:
The BOSU Ballast is a regular exercise ball containing weighted sand.
With help of this ball we can do a variety of exercises like crunches and some kind of squats.
Medicine ball comes in different weights and sizes and can add a fun element while working out on abs. We can bounce it, toss it or rotate it while doing exercises.
It is an incredible workout for the entire torso especially for the abs. If we use it regularly we can make a difference in both strength and functionality of abs. We can modify our posture as well.
