Ok i'm back!

WRT to heart rate, it's different for everyone. How old are you? There is a way to work out your best training zones if you can tell me how old you are. Also how fit are you? Are you a newbie...pretty unfit...what have you done in the past and how long ago?

It doesn't really matter what you are doing on the treddie as long as your hr is in the right zone. For example for you to get your hr to 160 you could be walking but for someone else they would have to be running iykwim? Interval training is the best kind of weight loss training I have found. EG 5 mins Xtrainer, 5 mins treddie, 5 mins rower etc.

WRT the classes as someone else said Step is not an easy class! I consider myself to be pretty co-ordinated and it took me at least 4/5 classes till I started to "get it" and a few months till I really, really got it! Pump is very different, you stand int he same place and don't move! Pump is fantastic for weight loss as it increases you lean muscle mass which has a higher metabolic rate than fat so the more muscle mass you have the more cals you are burning when you're doing nothing!

Seriously - give Pump a try.

Can't think of anything else at the moment. Howoften can you/are you going to the gym? Two Pump classes a week, 3 int training sessions and you will lose weight
