Paid hip/leg training for office workers

One action to solve the problem of working people do not have time to practice hip! 

With an elastic band, sitting in the office can be practised. Sitting anyway why not seize the opportunity to practice?

Method 1 (static version):
The elastic band snaps a little upwards at the knees, open the knees. Toes forward, use the strength of your glutes against the elastic band to keep it still and tighten your core if you have any strength left. 

Your back is reliable on the backrest, or slightly forward leaning (forward leaning will practice the upper buttocks)

Method 2 (dynamic version):
The elastic band stucks a little more upwards on the knees, lean forward a little and bend the hips. Toes forward, repeat to open and close knees. Use the insteps of your feet to turn to the sides and drive your knees out.
