The side plank is another great exercise that works multiple muscle groups and can be done at home or while traveling. The side plank engages your transverse abdominus, rectus abdominis, the internal & external obliques, the erector spinae, upper back, and deltoid muscles.
The side plank can help to improve core stability which makes you less prone to injury while lifting heavy objects or while twisting your body.
