low weights high reps and high weight low reps?

Question

Will lifting low weights for high reps give you muscle strength and lean muscles while lifting heavy weights for low reps will give you muscle mass and make you much heavier.

and for a 15 year old how much weight is considered high and how much is considered low?

Please tell me if this is true because it's confusing me and i dont want to start weights lifting before i find out.

Answer 1

Whether you "get big" or "get cut" depends more on your diet. More reps will increase muscular endurance (How long your muscles can excert force) More weight will increase your max strength (How much force your muscles can excert in a single contraction). It gets a lot more complex than that with how you put that together in sets and how you manage your rest between sets. Not to mention your exercise selection and frequency of your workouts.

There are an almost infinate number of workout programs out there to get you to any goal. At your age and experience level however, the most important thing to learn is good technique. You can check out the videos and explanations on the exercises page on http://www.crossfit.com They have one of the most complete and well put together lists of exercises I've found. NOTE: If you try their workout program, start off scaling it down until you are familiar with the movements.

Answer 2

No lifting heavy weights will not make you big and bulky as long as you do it properly remembering that you want to workout for martial arts and thereby revolving your workout around martial arts workouts....NOT like a bodybuilder

As for how much weight is considered high for a 15 year old I've seen 15 year olds lift 400 pounds with great form and some lift 20 pounds with horrible form...what I'm trying to say there is its different from person to person and you'll get stronger as you get older and more experienced, the trick is to do the proper exercises and not let gym 'experts' lead you to try the newest revolutionary exercise

That workout I sent you is actually built for mixed martial artists based on how much their base strength should be and what muscle groups should be strong

Answer 3

low weight is anything you can do 15 reps with and only find the last few reps hard

high weight is anything you can only do about 8 reps of.

you should aim for a balance. say a weight that is hard for 10-12 reps. the last rep should be painful to do so that you couldnt do another.

bt 15 is too young to get great results. its all because of testosterone. until you have that fully in your blood, you wont get great gains at all. you can get endurance, but not the mass. in a few years you will notice the difference.

you need to eat more too, if you want to pack on muscle. but 15 wont have you growing huge yet.

Answer 4

Yes, the first part of your question is true. And the weight limit has nothing to do with age. Are you already a stocky person? If so, that's what would determine how much to lift. If you're already toned and cut, go for more weight less reps. But also, at such a young age, you may not notice much. So do go kind of light and easy.

Answer 5

It all really depends on what you use your muscles for.... Im a distance runner so i pretty much just go around to like every machine in my schools weight room and bust out like 60 reps in like 3 ish minutes whereas my one friend who is a football player cranks the weight to as high as he can go and just maxes out... its also really important to not rush lifting weights.... each rep should take around 4 or 5 seconds and you gain the most muscles when you are letting the weights reset... not when you are pushing/pulling up/out so make sure you dont just let it drop back into place

Answer 6

15 is still pretty young to start working out very seriously, your body is still growing by leaps and bounds so there are still a lot of changes in muscle structure and strength to come...I would suggest to start off very very very slow to assess your strength and endurance....The answer to both of your questions will come mostly from your diet...if you're loading up on calories with high protein you can put on some pretty good muscle mass, with your 15 yr old metabolism however, you might have a problem with that and you'll eat your parents out of house and home....From my personal experience i wasn't able to start putting on good mass until i got around 17 closer to 18....start off slow and dont get discouraged if you can't do many reps or a lot of weight, it will come with time as will the size/tone.....try alternating workouts between high reps and high weight once you get some time under your belt.

Answer 7

i found alternating is the best way to go.im not sure about 15 years old but i would consider 20-25kgs(44-55lb)to be plenty when your doing low weight high reps.i used to do 5 sets of 20 at that weight and in between do sets of 75 kgs x 10.you need to build up to that though.i used to do that twice a day as well as run 30kms twice a day.that will give you plenty of fitness and strength.but it is important to build up to it over a period of time.i would also suggest buying a proper running machine to avoid back,knee and ankle injuries due to pounding.also a running machine gives you better running technique which helps more with the amount of muscles your working.make sure to do a small workout and stretch before and after.

Answer 8

low reps and high resistence is proven to burn more calories. But realistically you should be doing both and rotating, doing fast reps one day, slow the nexxt, heavy one day, then lighter another. As far as what is good for your age that is not the important thing for now, impotant thing is you don't quit and you gradually keep getting stronger little by little . If you are really into it, go to 7 11 for a fitness magazine, those guys are a wealth of knowledge and will get you on your way good luck

Answer 9

Heavy weight is what is considered hard to lift comfortably.If you can lift it easy then it is to light.If lifting involves a lot of straining then it is to heavy.Find a happy medium,and stick with it for awhile.If your sore the next day then that is about right for you.If you hurt really bad the next day then it was to heavy.Light weight many reps will cut you up,your right.Heavy will produce mass.
