8.5.7.2 VECTOR LEG FLEXION
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 5.5).
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
