To avoid cellulite on my legs I run 3 times a week, also I have a contrast shower every evening, some times if I'm not very lazy I do it in the morning too. It's very necessary to make a massage on the hips and legs with ant cellulite cream. I always do it for 10-15 minutes, do not use a towel just apply cream and start massage. It's like a little training every day. It's also very important to make it every day! And if the massage is not enough add walking for 40 minutes before the contrast shower and massage with cream.
The cream is not enough to get rid of cellulite, but it works very good from the outside, makes skin even and elastic. The physical training such as running, walking and even a massage for 15 minutes help inside-out. As for the creams choose the brand you like, I like L'Oreal. The main action of such cream is making your skin beautiful and improving circulation of the blood. So if you do all together it works perfectly. Hope my recommendations will be useful.
