Some good exercises for weak legs include knee marching, calf raises and lunges. These exercises are low-intensity options for those recovering through rehabilitation, children or the elderly.
Knee marching involves marching in place slowly while making sure the knee gets as high as possible. This exercise strengthens ankles, hips and quadriceps muscles and also helps with balance issues.
The calf raise exercise works and strengthens the calf muscles and enhances the ability to push off during running and walking. This exercise involves standing and slowly sliding up to the tiptoes repeatedly.
Lunges work the quadriceps while strengthening balance. This exercise involves taking a step forward with the hands on the hips and placing weight on the forward foot.
