LEG EXTENSION 4000

Start position
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. Position your feet behind the foot
padding so that the pad is in the same height as your ankle joint. Hold the
handlebars with both hands (also see Chapter 5.4).
2. Extend your legs upwards in front of you until your knees are almost completely
straight. Make sure that the motion originates in the knee joint only and that your
knees are not hyperextended. Breathe out when you exert strain against the
resistance. Maintain this position momentarily.
3. Now return your legs to the start position. Stop the return motion once your knee
joints reach an angle of approx. 90°. Breathe in during the return sequence.
