i recently cancelled a gym membership too. i find it's boring. i find i'm more motivated or inspired to exercise outside like on the beach or in a forest and as for weights, i know some people like them but i find that the best thing is using your own body weight. push ups, sit ups or any cardio like swimming. i think pilates is not bad too. i got a book from the library called yoga for regular guys. it's written by a famous wrestler in america who does yoga for strength. theres alot of good stuff in there you could try. keep trying new fun things to keep you motivated. i want to get one of those exercise balls. they seem fun
i just had a look at rebounding on youtube. definitely gonna get a little trampoline soon.
