Reps are an abbreviation of repetitions. In weight training you do one exercise and repeat it a certain number of times, say 10. Then you relax a brief period of time. Then you do a second set of 10. Then you rest. Then you do 10 more reps.
The term "reps" is actually a short way of saying "repetitions". Reps are the number of times you perform a complete action (for a bench press, you push the barbell all the way up and then bring it all the way down, that's one rep) during a set. One set is the number of reps you perform without any rest (longer than a second or two) between each one. The term "1RM" means "one-rep max", which means the most amount of weight you can move through one complete rep of the exercise, with no intention of doing another rep.
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.
Heavy Weight, Lots of Sets, and Low Reps.
Generally a good workout weight is the weight at which you can do at least 8 reps but no more than 12 reps. If you are able to do more reps, try going heavier. If you are training for strength, use fewer than 8 reps but go heavier on the weight.
You are asking the wrong question. Normally when you can get to 10 reps it is time to add more weight. Now you should go to 60 pounds. The object of weight training is to add strength.
Yes, dumbbells are a good source for strength training. For strength training you will need to work on less reps with more weight and slowly increase that over time.
You have to be careful weight training at that age, because your bones are still at a formative stage. Some limited weigh training is fine, but you would be better advised to get for low weight high reps, rather than high weight low reps.
more weight less reps more weight less reps
If you want to lose weight cardio is best.To tone you need to do lots of reps of a weight that is not too heavy for you to do lots of reps.To build muscle like how bodybuilders do, you need to do a few reps of a very high weight.But it sounds like you want to tone and lose weight so do cardio, but also tone with lots of reps at not a high weight.
To lose weight you want to do endurance training. Lots of jogging and crunches. If you would like to use weights use an amount that you can do 20-30 reps with.
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.
