Going up the stairs is great for your legs because it lifts all your body’s weight at once. It burns calories and gives you an added workout for your leg muscles.
Exercise legs once a week
Weight training isn't as rigorous a legs workout so give yourself a week to rest before your next legs workout. You need to allow the torn muscle tissue to recuperate.
Squats and leg presses
Don't lock out at the top of squats and leg presses. If you do, it will put too much pressure on your knees, making the joint vulnerable thus making it easier to be injured.

The wrong way to do leg presses
If you lower the weights too far, your lower back will start to lift off the pad. At this point you know you’re exercising the wrong way.
Leg positioning
The higher your foot is on the platform the easier the quad because it’s contracting less, the less your knees are involved in the exercise.
