There are several factors involved in getting stronger muscles, not just lifting itself. The amount of reps you're doing, diet, and the consistency with which you lift are all factors.
More reps will build muscle, not more weight, after a while you can add more weight and more reps.
more carbohydrate on a runner - needs a lot of energy consumption. More protein diet on a weight lifter - need to build muscle to lift bigger weight.
you can lift any weight as long as you don't strain yourself too much.
It depends if you get fat then go on a diet, or if you lift weights, you gain muscle,and muscle weighs more than fat.
Protein is an important factor in gaining muscle. Eating more protein and drinking protein shakes will help you build lean muscle without losing weight. It is also important to be consistant with the amount of weight you lift and the number of reps you do.
strength training helps get more muscle by recruiting more muscle fibers depending on the amount of weight you lift .as you add weight you call upon more motor units to innervate new muscle fibers.these muscles fill with blood that is hypertrophy if not used then atrophy will happen.shrinking of the muscle.
you muscles are made of many individual muscle fibers. When you lift a weight or exert a force over and over again you damage these fibers (more specifically actin and myosin). When your body repairs the damage, you get more muscle mass!
it is proven that you can lift your weight or more And you can push nearly 2 times more with your legs!
No, you don't need to increase your caloric intake while on a weight-lifting regimen. I would recommend upping your protein and carbohydrate intake though. Protein = muscle repair Carbs = Energy to weight-lift
The average arm muscle size for a 18 year old male is 14 to 15 inches. The more you work out/lift weights, the more your muscle size will improve.
It is because your muscles are used to being worked hard in your dominant arm. When you lift the same weight the left muscle, or your opposite side, gets a better workout and the muscle tears more which ultimately results in a bigger muscle. The dominant arm is still stronger due to years of gradually developing strength.
If you are interested in building muscle you should gradually increase the amount of weight that you lift on dumbbells. If you are interested in toning and firming your muscles you should have less weight on the dumbbells and do more reps.
