Sit on the assisted leg press machine with your back supported against the pad. Place one foot firmly in the center of the platform while the other leg is off or supported. Press the platform away by extending your working leg, keeping your knee slightly bent at the top. Slowly lower the platform back down until your knee reaches about a 90-degree angle. Maintain controlled movement throughout, then switch legs after completing your reps.
Log your assisted single leg press sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
