Question

What help to maintain the flexibility of the knees?

Answer 1

Answer:

If your knee's not at its best, start with a simple strengthening exercise for your quadriceps, the muscles in the front of the thigh. This move puts little to no strain on the knee. ... Keeping the other leg straight, raise it to the height of the opposite knee. Repeat 10-15 times for three sets.

Answer 2

Answer:

Stretching exercises help keep your joints and muscles flexible. Standing quadriceps stretches can reduce muscle fatigue and soreness at the front of the thighs. Hamstring stretches can keep the muscles at the back of the thighs and behind the knees loose.
