I go to a gym, and trainers are very exspensive. At my gym they have a certain amount of classes that you pay for. If you have one, you want to make sure they stay with you during the workout. I will tell you that when you have one they are going to make the sweat roll off of you. I have been going for a little over 2 months, and I have lost 2 dress sizes, and I have worked really hard to do it. If you keep going on a regular basis your body will get use to it. I usually do at least 1 hour on hard cardio. I like doing 2 hours and doing the weights. I don't do the free weights. They have a bunch of different weight sets that you can do. They should have classes that come with your membership. I would just say that if your just starting, start with a lower machine that is not so hard on cardio until you get your heart, lungs, and muscles use to it. A treadmill would be good to start with. The ellictipals are hard. And if your like me, and don't know how to use the equipment just ask. Good luck and keep posting so we know how it goes.
