http://AskTheTrainer.com Personal Trainer Michael Behnken, MS, NASM-CPT-PES, CSCS Total Gym supine lateral raises are a tough version of lateral raises. You see the very low level which is challenging. Having your body at a slight decline angle can be an advantage to pumping your muscles up according to an old bodybuilder friend of mine. The total gym lateral raise would be a great exercise to finish off a lateral raises because the extra blood would be flushed into your deltoids. There is no scientific research behind this, bodybuilder lore, but I personally like it. NOTE: This exercise is performed on the GTS which is the gym version of the home total gym.
