You have been inside your home for more than a month. This means less physical activities like walking, running, swimming including other exercises. Being less active can have a major impact on your knees. It may lead to knee stiffness and cause pain in the long run.

The best way to prevent this is by incorporating a few exercises in your daily routine.

1. Straight Leg Raises

It is a very simple exercise and doesn't put much pressure on your knees. Just lie on the floor, keeping one foot flat on the surface and bending the other one. Now, raise the resting foot to the height of the opposite knee. Check this out to understand it better.

2. Standing Hamstring Curls

This is also a very simple exercise but super effective. You don't have to bother about any equipment in order to do this, you don't even need a yoga mat. Just stand straight and lift one knee at a time. Here's the full procedure to carry out this exercise.

3. Wall Squats

Simple yet powerful. This exercise helps your upper leg muscles a lot. You just need to stand against the wall with your feet out in front of you and squat. Check out the proper steps here.

4. Calf Raises

It is a great stretching exercise for leg muscles. This exercise is generally done by raising the heel as far as possible. Weights are commonly used, but the exercise is also effective with body weight alone. Here's how you can do it properly.

This is a fun exercise. Just use a step or platform (even staircase) raised high enough, and place your foot one by one. Now, what can be simpler than this! Check out the proper steps here.

8. Half Squats

It's a variation of squat that focuses on your hip and knee joints and strengthens your quadriceps, glutes, and hamstrings. Here's how you reap benefits of this easy exercise.
