Exercises for keeping your legs tonedYour legs tend to take a lot of hammer when you sit all day, so let's look at how we can rejuvenate them.Turn your Office Chair Singapore to one side so you have space to stretch out your legs with feet on the floor. Lift your right knee upwards and grasp the front of it just under the knee with both hands. Pull the bent leg towards you gently and hold this position for about 20 seconds. This will get a good stretch into your leg muscles. Lower your leg and relax and then do the same for your left leg.Next, again sitting to one side place your legs out in front of you with feet on the floor. Place your right leg over your left leg so you are sitting cross legged. Take your left hand and grip the outside of your right knee pulling it to the left. At the same time turn your head to look over your right shoulder with your right arm by your side. Hold this position for about 20 seconds and then return to your original position and relax for a few moments.Repeat the exercise for your other side.
