Description
Quad isolation in a corner-sized footprint — £480 with free UK delivery. The Attack Strength Sissy Squat holds the lower leg vertical through a full squat motion, so the quadriceps take the entire load and nothing else can assist.
What does a sissy squat do that a squat or leg press cannot?
It trains knee extension with the hips held in line. In a barbell squat or a leg press the hips flex, so the glutes and hamstrings share the work; here they cannot. That reaches the part of the quadriceps hardest to load, particularly the rectus femoris, which crosses the hip and is under-trained by every hip-flexing movement.
Do you need the frame, or can you do it unsupported?
You need the frame. Unsupported sissy squats — feet hooked under something, leaning back on faith — put unmanaged shear through the knee and there is no way to bail. The 25° adjustable foam bar and oversized pads fix your shin angle and your ankle position so the movement is repeatable rep to rep, which is what makes it trainable rather than a party trick.
How do you make it harder once bodyweight is easy?
Use the belt hook. A dip belt with plates hung from it adds load without changing the movement, which is the correct progression — slowing the tempo or adding reps changes what you are training. Most users reach that point within a few months.
