5. Squats using Swiss ball
If you have weak knees, this is the best leg workouts for women that will help you. The Swiss ball here will act your stabilizer and decrease the pressure to your joints. What you need is a wall in which you can press against the ball. Stand up properly with the ball positioned in the lower back in a wall. Cross your arms in front of your shoulder and squat down. Count to 10 until you reach the 90-degree angle of the squat and another 10 to go back to the starting position. Repeat this without resting for three times.
