This may not answer the question specifically, but really not that long for each work out, but I believe you will see growth within three months.
Yes, it is possible to build muscle with dumbbells. Dumbbells are considered a "resistance" training method and help build muscle substantially.
Not really, to tone your biceps you need to be lifting heavy weights so that you put stress on your muscles, your muscle will then grow bigger to adapt to the amount of stress you are putting on the muscle.
Not really, because at one stage your body will get adapted to 7kg dumbbells and in order for the muscle to keep growing, you have to increase the weighs.
To start, one set of low weight, maybe one or two pounds, dumbells are all that is needed. As it becomes easier to use the lower weight ones, move up to 5 and then even 10 depending on how large one is trying to build the muscles.
The difference between muscle mass and muscle hypertrophy is that muscle hypertrophy is the increase in size of skeletal muscle while muscle mass is the weight of your body muscle.
Lifting weighs refers to picking up dumbells from the ground in order to gain muscle mass. A treadmill is device that allows a person the ability to run indoors.
contracted muscle and relaxed muscle whats are the difference? contracted muscle means its very very contracted and relaxed muscle means its very very relaxed
Nope, you need protein for muscle gain but you DO need some fat from your meals to supply yourself with energy; both for staying alive, and to lift those heavy dumbells :)
Lean muscle is dense.
i don't no what is the answer?
A deep muscle is deeper in the body and a superficial muscle is closer to the surface.
no difference
