Isometric Abs!
Isometrics hold muscles under tension for a set period of time. Try this V-Sit for an isometric abdominal challenge. Here’s how:
Sit on the floor in proper spinal alignment. Pull your belly button in and keep your shoulders back and down. Extend both legs straight out on the floor in front of you. With a straight back, lean back slightly and lift both legs up off the floor about 6 inches to start. Extend both arms straight out in front of you. Hold this position for 10 seconds, breathing in your natural rhythm. Lower your legs and rest. Repeat 2-5 times.
*Consult your physician before performing exercise. This exercise is for intermediate/advanced exercises, and is not for those with injury concerns.
