Since you do not want to damage the growth plates on the ends of your arm bones and leg bones, you would be better off lifting every other day with weights that you can do for 20 to 50 repetitions before exhaustion. It is important not to max out your weight, but for bulking up, you do want to lift to exhaustion, that is, the point at which you strain with all your strength but cannot lift the weight any longer. BE SURE to warm up for 15 minutes with light weights and 30-second stretches before you start with serious weights!!!
Keep the muscle moving or rub it to avoid lactic acid buildup (shich causes sore muscles), then do another repetition to exhaustion. Finish with a third rep to exhaustion, or until you muscles feels "pumped up". Warm down with much lighter weights long enough to move the lactic acid out of the muscles, say, 10 to 15 minutes or longer.
An hour per muscle group is plenty at age 15.
As long as it is not too strenuos it shoulf be all right.
No it does not its the other way round Jenny and the team
Not necessarily, if you lift lighter weights with more reps then you will develop long lean feminine muscles. If you want more masculine and defined muscles then lift a heavier weight with fewer reps.
you should wait about four to seven days at most
If you are asking "What is the maximum time a single weight training session should last?" the answer is "about 45 minutes." Individual differs. Some people can train longer without wasting time and still be productive. If you are asking "How long in life should you lift weights?" the answer is "as long as possible." It has been proven that even people in their 90's can benefit from weightlifting.
Well, its takes alot of effort. First you have to work out a ton. And it depends what part of your body you wanna make stronger. You have to lift weights and go on long jogs and you dont have to eat a ton like people say your appetite automatically gets bigger as you do!
You can do this, but it depends on the time, With all excersise you have to work p to long periods of excersise. For example you cant expect to go running for about 3hrs and wake up the nxt day ready to lift alot of weight. Start off with times and weights u find easy and as they become easier, go for longer.
your growth most likely will not be stunted, as long as you still get about 8 hours of sleep lying down every night
almost 30 hr of 1 hr increments but mix it up do sit ups and pull ups one day and lift whegts the next but dont lift to much just get about a pound more every time.
That depends how many pounds you are lifting, how often you lift, and how many reps you do. I would say about 4-10 weeks.
The males and the long beard braid is in charge. they have to buff as well.
I don't think your muscles actually shrink and keeping it at the same weight will continue to increase your strength but after a long time it will have only a little effect, I recommend only changing them when you are finding it stupidly easy to lift the weights.
