The assisted inverse leg curl uses a counterweight or resistance band to make the bodyweight nordic-style curl achievable for lifters who cannot yet lower themselves under full control. Anchoring your ankles and lowering your torso forward trains the hamstrings eccentrically, which is one of the most effective ways to build hamstring strength and reduce strain risk.
Log your assisted inverse leg curl sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
