Keep torso on bench to reduce hyperextension of the lower back. Most machines are angled at the users hip to position the hamstring in a more favorable mechanical position. If angle is much greater, the Rectus Femoris will less likely be involved as an Antagonist Stabilizer.
Trunk curls are the only exercise which effectively isolate the abdominal muscles. All other abdominal muscles - e.g. sit ups, leg raises, etc. - primarily work the iliopsoas muscles of the hips, not the abdominals.

Leg curls may be integrated into a workout in many ways. One way is to do leg curls as a part of a more extensive lower body workout. Another way to integrate leg curls is to alternate them with upper body reps such as tricep pulls.
The best way is to go to a gym and work out on the machines to do exercises such as hamstring curls, leg extensions, leg presses and squats can be done without machines. But you should get instructions on how to do them properly by a professional trainor.
there both leg execises
Squats, leg curls, running, swimming
I like to do hamstring curls to work the lower part of my hamstrings which dead lifts don't really touch. But my gym is gay and only has those seated hamstring curl machines where you actually SIT on your hamstrings, the most stupid thing i have ever seen, yes sit on the muscle you are trying to work. Anyway I can do improvised curls on the leg extension machine, if I face the seat.
The muscles used in the leg press exercise are your Quads primarily. Hamstring gets a good work out too.
You need to eat big and exercise. Eat 1 gm of protein for every pound of your body weight. Work out legs once a week. 2 warm up sets - Squats - light/ moderate weight - 15 - 20 reps 4 sets of Squats/ Hack Squats 4 sets of Leg Press 4 sets of Leg Curls 4 sets of reverse leg curls For the work sets, take a weight which you can barely do 12 reps.
By doing leg strengthening exercises like: * Squats * Leg Press * Leg Extensions * Lunges * Hamstring Curls * Calf Raises * etc.
Most muscles in the body have "counterparts", one pulls and your leg curls up, the other pulls and the leg straightens. They would be on opposite sides of your leg. The "biceps" are the upper arm top muscle, and the tri-ceps (I think) is the upper arm bottom muscle. They work in conjunction to let you 'curl a barbell'' or do a chin-up.
Wrist curls are a good option.
