Hi, i am a regular at my local gym. body fat is 8% and i have been going for body pump. will this make me lose my muscle mass due to the high reps?

No it won't, BUT I would also work into your exercise routine regular lifting 6-12 rep range with heavier weights to keep your mass up

Short answer...I agree with the previous poster.

Longer answer...I reckon you should be OK if you work hard enough. It's always good for people concerned with muscle mass to remember that your body doesn't really like you having large muscles, because the body has to spend more energy than it wants to when it has to maintain those big muscles.  But if you work hard enough for long enough, your body will realise that it's going to have to let those muscles get bigger if you are going to keep doing all this heavy strength work. (Basically, that's why people who start training get stronger before they start getting bigger).

There is an overlap between a hard Pump workout and general mass-building workout, so Pump shouldn't make you lose too much mass.   I would recommend really squeezing a muscle during the contraction phase while doing a Pump workout.  Especially when the Pump weight is a lot less than the target muscles would otherwise be able to handle (eg dead rows). Squeezing is important because effective weight training is not really about lifting a weight from point A to point B...it's about contracting a muscle.

As the previous poster said, an additional heavy session once in a while wouldn't hurt. Pump moves are much lighter than conventional weights movements and also travel through a shorter range.  This is an important thing to note because your body (again...in the interests of saving energy whenever possible) will only use as much muscle as is necessary to lift a weight. When you do a biceps curl, not every part of your biceps muscles contract...the more weight you lift, the more of the muscle contracts.  Also, the greater the range of movement you use, the greater the amount opf muscle that contracts.   So a Pump curl, for example, will tend not to use as much of the muscle as a heavier gym curl might (all other things being equal), even though the biceps might look as though it's all contracting.

hi mate,

 

would love you to do an assessment and then after six weeks of bodypump get another done and let us know the results. Make sure its the same person doing the measurements/body composition etc.

okay thanks guys :) i wont give up my body pump :)
