A300 Leg Curl Pro

TRAIN THE HAMSTRINGS TO FIRE PROPERLY

Training hamstrings at speed trains the brain to better control the firing of the hamstring, helping to prevent hamstring injuries. The A300 Leg Curl Pro features improved ergonomics with the chest pad, thumb buttons and display in more comfortable positions. 

The independent motion of each leg allows you to train the same way you play. You can even train like a bicycle (as one leg is going up, the other is coming down). And don’t forget about the ability to eccentric overload, which has been shown to help prevent hamstring injuries.
