Leg curl machine at my gym has the support pad sit below the knee (see photo), which I feel offers little in terms of bracing/stability. I have to focus more on pulling my hips/butt down with the side handles than actually executing the leg curl. Additionally, it’s non-stationary so it rocks back through the movement.
Was wondering why the machine is built this way and what this offers, as well as alternative exercises to work the hams in mid range. I’ve mainly been doing to lying leg curls and RDLs as accessories on leg day and feel like I’m neglecting mid range for hams. Thanks
