HOW: Start by laying flat on your back with a band wrapped around your upper back at shoulder blade level. Hold the band in each hand between your thumb and index finger. Begin the exercise by first assuming a V up position with your legs - flatten your low back into the ground, lower your rib cage down, and flex your quads to keep your legs straight and lift them off the ground. While holding and maintaining this position, perform a chest press motion with the band by reaching your arms up and forward to get max tension on the band. Lower your arms down to starting position and repeat.
FEEL: This should feel like a full body workout. Your upper body working with the chest press whereas your lower body and abs working to hold the V up.
COMPENSATION: Do not let your low back excessively arch, keep your legs straight. The higher your legs are from the ground, the easier it is. Do not rush the chest press motion, maintain time under tension and slowly go through the movement.
