LEG FLEXION 4000
1.
Adopt the right exercise position: Sit on the seat so that your upper body touches
the backrest completely. The axis of your knee joint should be at the same height
as the rotation axis of the machine. Place your feet in front of the foot padding so
that the pad is at the same height as your ankle joint. Secure your legs with the
thigh restraint and hold the handlebars with both hands (also see Chapter 5.4).
2.
Bend your legs back and upwards until your knees reach an angle of approx. 90°.
Breathe out when you exert strain against the resistance. Maintain this position
momentarily.
3.
Now extend your legs to the start position. Stop the return motion when your knees
are almost completely straight. Make sure that the motion originates from the knee
joint only and that your knees are not hyperextended. Breathe in during the return
sequence.
Exercise variations:
You can also perform this exercise with only one leg. This prevents the
stronger leg from performing more of the work.
Principal muscles worked:
M. biceps femoris
M. semitendinosus
M. semimembranosus
