8.5.7.1 VECTOR LEG EXTENSION
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 5.5).
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.
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. quadriceps femoris
