The Hammer Strength MTS line made some very cool machines. The independent weight stacks is an ideal way to train accessory work. It fixes imbalances between our dominant and non-dominant sides. This is a very unique machine. You really feel it in the biceps femoris – the big, meaty part of the hamstring that’s on the outside. It’s rare to find a hamstring curl that hits there. Of all the MTS machines, this is probably the toughest keeping in unison when you do both sides at the same time. That probably makes it extra necessary. It’s definitely one of the best seated hamstring curls of all-time.
