Leg Cross
With a seated leg cross, you can strengthen all muscle groups around your knees and improve its range of motion. This exercise mainly targets the entire leg, particularly quadriceps. The first step is to cross your ankles over each other and contract your thighs. Keep this position in 10 to 30 seconds, then switch to the other side. Do this exercise 3 to 4 times. An alternative option is to repeat these steps with outstretched legs. This can be great and simple to do anywhere you want. [4]
