Mark Bell's Sling Shot and Sling Shot products are sold by Super Training Products, LLC. Their first product, the Original Sling Shot was invented by Mark Bell as a way to train the bench press while hurt. They work by stretching with you as you lower the weight to your chest, then when you are at the bottom of the lift, the Sling Shot gives you a little extra spring that allows you to get the weight moving again and complete the lift. All the models can also be used for assistance with pushups and dips and allow you to do more reps. 15 Howmuchyabench coupons, including Howmuchyabench coupon codes & 12 deals for December 2017.
