My fav AB Exercise!!

The Jacknife - I love it becuz it can be done anywhere and you can make it harder by adding pulses (pilates style). I do a set of 15 jacknives with 10 pulses. Start the movement arms overhead and legs extended. Raise your arms and legs at the same time,[shoulder blades off the mat] bring your hands down by your sides (palms facing down) pump your arms for 10 reps and return to starting position. Repeat this 15 times with 10 pulses (or pumps). Do 2 to 3 sets in between your workout! Burn baby Burn!
