Last June I decided to get serious about weight loss. I am plus sized. So, I went to the gym (we have a place called LA Fitness) and signed myself up. The first month all I did was water arobics. Every night for an hour. They had classes there. I think in the first two months I dropped 28lbs. Granted, I also DRASTICALLY changed my diet.
Then I slowly started onto cardio machines. I just walked first. Slowly! lol 1/2 hour, and then I would go and do a little bit of weights. When I started using the actual "gym" (not the pool) I was in there for about 45 minutes. As time went on I added things to my repetoir (sp?). I LOVED the eliptical. But, honestly, the first time I did that horrendous machine I lasted all of 3 minutes and thought I was gonna die. When I stopped going to the gym (April of this year, got prego and SUPER nasty nauseous) I was on that eliptical for 45 minutes! Then, I would go and do some stretches, free weights, and then back up for a cool down on the bike or walking (15 minutes). So, by the end of my gym time I was there almost 2 hours.
From June of last year until April of this year I lost about 105 lbs. Take it slowly, push yourself, but not to the point of puking or dizzyness (which I did a few times), listen to your body, and don't worry about what ANYONE else is thinking! That was hard for me, especially when I was lasting 3 minutes on an eliptical!! But you know what? Screw them all!! I was working hard for me and setting my own personal goals.
Do NOT just go to the gym, change your eating habits as well!!! Drink tons and tons of water.
Good Luck to you!
