Side Crunches

Intermediate Level of Difficulty

This is a core exercise that uses the rack to isolate the obliques and build strength and definition using your own body weight in a side crunch.


Picture of Obliques


Many people put a lot of focus on working their abs but forget their surrounding neighbors; the oblique muscles. Obliques serve as stabilizers, and are used in almost every physical activity. Exercising your obliques should be a very important part of your workout program.

Picture of Forearms


We don't often think about our forearms when we exercise. This is a little surprising as they are one of the most used muscles throughout our daily routines. Your forearms are involved in almost every movement especially when exercising. Every time you are required to grip anything with your hands, you’ll be using your forearms.
