What are the best games to get a work out BESIDES wii fit dance ones etc?

-i wanna get a good work out but not look silly and have fun. i play wii sports tennis allot and only get a little exercise wanna know if there are any FUN games that don't make you look silly (don't really want games designed to for you to work out like wii fit but if there are any really good ones just name them and ill take into account)a good one would be Wii fit... it has 3 sections, games, yoga, and like a workout one. you u can go from walking a tight rope to having a pushup competion with the computer so wii fit. if that is 2 expensive, pushups, they are free and an amazing workout
Any wii ones, boxing is good.
why dont you buy a gym set from a garage sale for 30$

go on youtube and type in work out exercises with dumbells
