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
