Deadlifts use most of the muscles in your body in some capacity, though the primary muscles involved in concentric contraction are:
and isometric contraction:
A wider foot stance will recruit the hips and legs more while a narrower stance focuses on the lower back. Deadlifts are also one of the best ways to improve grip, as long as you don't use straps and use a pronated grip with as heavy a weight as you can.
Deadlifts, along with squats (both with the barbell, of course), are widely considered to be the best exercises you can perform in terms of building mass, bone density, balance, and posture. In other words, if you're not doing these exercises, you're wasting your time in the gym.
Although a compound exercise involving a variety of muscle groups, the deadlift primarily works the lower region of the back (erector spinae). It however also involves the thigh (quadriceps), hamstring (femoral) and gluteus maximus (posterior) muscles. Still other muscle groups are recruited as stabilizers when one performs deadlifts.
suck a large penis
yes they do
The muscles of the chest, the triceps, and some involvement of the posterior (front) deltoids (shoulders)
Eat lots of lean protein and weight train.
This is a room with muscletrain stuff. You can train your muscles in a training room.
With stability ball exercises, you can train most muscles with various exercises, including the hips, thighs, upper back and abdomen. You can learn these exercises online at the Ball-Exercises website.
I would recommend not 3 exercises but 5. These are called the big Five. They are: Squats, Deadlift, Bench Press, Press, and Rowing. The protocol you use to do these exercises is up to you (but I recommend deadlifting at the most only once a week).
Sit ups train the abdominals when performed properly. They also train the back muscles too. There are many different variations to work different muscle groups.
If a person exercises a lot, he or she will not only train his or her muscles, but also his or her lungs. And since the lungs are surrounded by muscles, you train these muscles too. So a marathon runner has stronger lungs, that have a bigger capacity, as the muscles that surround can contract and stretch farther than those of a nonactive person.
Basically all of them in some way, isometrically. In other words, they shouldn't be lengthening or shortening, or you're doing them wrong and you probably have already hurt yourself. Deadlifts train most muscles in the body, and yes, they're excellent for all muscles of the lower back.
well, try to lose weight normally and train your muscles because muscles add weight
It depends on what you are measuring because there are two types of muscles. If you are maxing and do 1 rep, then you measure your muscles' explosive capacity. If you do several reps (>8) you train your endurance instead. There is a fine line between endurance and explosiveness, but generally you can say that if you train 1-6 reps, its more explosive training. If you train 12-20 or more than that you train endurance. Between 8-12 you train both.
