Cardio Energie

I’ve been doing 30-40 minutes, six days a week on a cross trainer for almost a year and been really pleased with the results. Legs, shoulders and arms have really toned-up and my cardio fitness is much better. I started using 1lb wrist weights and noticed an improvement pretty quickly. I have just got some 2.5lb weights and started using them, but I don’t want beefy arms, just toned arms. Will they be OK? I’m 49kg, 5′4″ and a pretty lean build.

I have an old knee injury (broken knee cap about 15 years ago) that left my leg in very poor condition for about 2 years. It then used to dislocate and lock constantly. It has been fine for the last three or four years however (although it still aches sometimes). I do a lot of cardio on treadmill/bike but recently was told that the cross trainer would be better for my knee. I tried it for a few sessions (of only about 10 - 15 minutes per session) but found that my knee was very painful afterwards and my toes started to go numb on the bad leg. Am I doing something wrong or is this a common problem?

I am building a GYM at my Hotel and I need the best of the best

1. Cross trainers
2. Elliptical machines
3. Stair climbers
4. Bikes
5. Treadmills

The reason I ask is because I just got a great deal in the mail for a fitness club membership and I’m seriously thinking about joining. I’m not overweight, but I do have a little fat … a little … to lose around the belly area. I want to have my six pack showing by hopefully August. I checked out the website of the club and this is the equipment it listed for cardio exercises.

By the way, I don’t even know what a cross trainer is. If you can paint a picture for me, that’d be great.

So, which one burns the most fat? Thanks!
