I am doing the 30 day challenge on the high intensity workout. For those of you new to fitness, I would recommend you to start at the lowest level. It is much better than the Wii Fit which I also have and it is much cheaper. You will really sweat unless you aren't working properly. I am about 8 days into the challenge now and boy am I feeling it. My arms are really toned now and the great thing with Sports Active is the exercises change all the time so you don't get bored. You really feel as though you are there whether it is on the basketball court, on the track or doing some dance moves. The calories you burn are displayed on the screen and there is an on screen trainer who shows you the moves. There are also videos you can watch to make sure you are doing the exercises correctly. I was introduced to the squat hold today where you have to squat down and hold it for a minute. Really hard but I managed it twice and I'm 41 with 2 kids. If you are only thinking of buying one game, I would get this one as you will feel the benefits. You can take the lifestyle survey where you say if you have eaten the required portions of veg and if you have done any other activities etc. A good motivation with this is you collect trophies as you go along. Go on, treat yourself, your body will love it! You can do it in the comfort of your own home and you get rest days. Buy it now, you won't regret it!!
