Olympic and NHL trainer Michol Dalcourt invented the ViPR to mimic the odd-shaped loads he lifted while growing up on his parents' farm – bales of hay, bags of feed. Think of these weighted rubber tubes as something between a barbell and a sandbag, meant to enable what Dalcourt calls "loaded movement training" that closely mimics the strength work of everyday life.
Try: Cylinder Lift
Stand with feet shoulder-width apart and a ViPR held vertically in front of you, hands wrapped around the top of the tube. Now "throw" the tube upward and catch it in the middle, then throw again to catch at the bottom. Drop and repeat.
