Weak knees can be debilitating and the best way to overcome the pain is to strengthen them with these exercises. Weighted Calf Raise Many people complain of knee problems and there are some exercises that one can do to alleviate such issues. Weak knees occur due to three main causes, illness, injury or overuse. To accurately identify the reason and corrective measures for your weak knees, one should first consult a doctor.

If the doctor prescribes strengthening exercises as a corrective measure for your weak knees, the focus must be on strengthening the surrounding muscles ie. the quadriceps, claves, glutes and hamstrings.Weighted Calf RaiseMain muscle: CalvesEquipment: Smith MachineSet the bar on the smith machine to around shoulder height and rack up the weight you want to use. Grab a step or calf block and put it below the bar. Step up on the block and position the balls of your feet on the edge. Grasp the smith bar with a wide grip and position it across the top of your back muscles (not across the back of your neck). Push up to take the weight off the rack and slowly let your heels drop down as far as possible. This is the starting position. Slowly raise your heels as far as you can off the floor. Squeeze the calf muscles, and then slowly lower your heels back to the starting position. Repeat 10-15 times. Alternatively, if one does not have access to a smith machine, the same movement can be performed standing at the edge of a step (preferably, first step on the staircase to avoid any risk of injury) and use the body weight as resistance to perform the exercise.Step-UpsStep-UpsMain muscle: QuadricepsEquipment: Stepper/ stair/ benchPlace one foot on a step bench, platform or a step on a staircase.

This will be your starting position. Using your quadriceps, extend (straighten) your legs to the maximum as you exhale. Ensure that the rest of the body remains stationary on the seat. Pause a second on the contracted position. Slowly lower the weight back to the original position as you inhale, ensuring that you do not go past the 90-degree angle limit. Repeat 10-15 times, on each leg for three sets.
