Twisting Swiss Ball Jacknife
Concentrate on keeping the body straight during the entire movement. Keep the hips in the proper position to maximize the training benefits. Fatigue will bring the hips towards the floor into a poor position.
Aim to bring the knee towards the opposite shoulder and squeeze the oblique muscles at the top of each rep. A anti burst swiss ball is required for safety.
Personalized weight training, interval sprint and nutrition program clients should perform the number of reps listed for each set for both the left and right side. Alternate sides with each rep.
