Somethings that I have noticed on my health and fitness journey:
3 reasons why the Leg Curl Machine can be absolutely horrible:
Reason #1 Almost impossible not to arch your back and train the wrong area of your hamstring, with a lot of pressure on your spinal discs. (your laying on your abs, this is not an ideal position for training)
Reason #2 You’re working the wrong part of your hamstrings (your lower hamstring not the upper, which isn’t very functional and misses the majority of the metabolic effect.)
Reason #3 Your hamstrings and abs counteract each other, to stabilize your spine, because you’re laying on your abs, you’re guaranteed an imbalance. These imbalances can lead to back and hip injuries.
