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.

Relax upper body
When lying down try to let loose. If your body feels tight and rigid it will affect the hamstring stimulation in a negative way.
Easier leg curls
You can grasp the handles, which are generally given. Make sure you hold lightly. This is to ensure that the focus of resistance remains in the hamstring muscles and makes it very beneficial.
