I read a Frederic Delavier’s book « Strength Training Anatomy » and I learned good stuff.
Sitting on the machine with your hands on the handles or the seat to keep your torso montionless. Your knees are bent and your ankles are under pads :
Inhale and extend your legs to the horizontal.
Exhale at the end of movement.
This exercise is great for working quadriceps. The more the seat’s back is inclined, the more the pelvis is in retroversion. This has the effect of stretching the rectus femoris muscle which intensifies the work of quadriceps during the leg extension.
This exercise is recommended for beginners to gain strength to do exercises more technical later.
