it will build your muscle up as low weight with high reps will tone the muscle out.it wont build it.
burning fat.
I was always taught that low weight with high reps is for weight loss and toning, whereas high weight and low reps is for strength training and bulking up.
low reps, high weight
Bleep test. You can also test muscular endurance by doing weights using low weight, high sets and high reps.
High weight and low reps with help build the muscle and make them more predominant. Building up the ab muscles will really help them stand out.
When I was in my late teens I was very much into powerlifting and bodybuilding. My coaches stressed to me that to build muscle you need to lift heavy weight with low reps (4-6 reps) and to tone your muscles (shape them) you need to lift lighter weight with high reps (10-12 reps). So, I would train each body part twice per week (once heavy then once light). I got great results using this formula as it helped me get stronger and well defined.
For muscle size: high weight, low reps, rest low reps, rest... Use as much weight as possible, so much that you can only lift it a couple times. For muscle toning, endurance and general health, high reps, shoot for 20 or more before the muscle is fatigued.
It depends what you want to do. I use a cobination of it. I would so 4 sets of 8 and the last set that you do, you need to make sure that you can barely get it but you can get it. If your just trying to get cut but not big, then just do reps, but if your trying to get big and cut then you need to do alot of weight and about 8 reps to 10 reps and do 4 sets of them.
It depends on your desired results. For getting stronger and bigger, use a lot of weight and low repetition. I would recommend 2-3 sets of 8 reps with however much weight you can handle for that amount. For getting more toned and gaining endurance, use low weight and high reps. I would recommend 3-4 sets of 12-15 reps.
it depends on how heavy u are lifting and how often, i have been weight training since i was 10 years old, along with running and rugby. my muscles r alot mur developed than my friends and allot stronger. you must make sure that you are doing low weight but high reps. e.g start on a low weight that's right 4 u and lift 15-20 reps. and as you get older you can start getting higher weight lower reps like me. goodluck
Heavy Weight, Lots of Sets, and Low Reps.
it depends on how much weight your working out with. if you are using a weight that is challenging and only you can do 3 to 5 reps you are using the right weight if you want strength.. you should use low reps because it stimulates your muscle fibers faster and more rapidly then higher reps. higher reps=more muscle endurance, and more definition. Lower reps= strength and muscle mass. you will gain strength quicker with weight that you can only do low reps.
