Need a new fitness challenge, any ideas?

I'm sick of the gym, I've tried out a few classes at my local leisure centre and found out that I definately do not like Zumba, I have the urge to try something new but have no ideas. I can't run far because I've torn a muscle in my back and I don't own a bike. Any ideas would be greatly appreciated, I feel like climbing a mountain or something! lol!

Hi sugarlips , have you tried kettlebells great cardio and muscle defining

ripped DVDs are very addictive get a pre view from youtube, -jari love.

Or even yogalates get 2 hits in one, flowing movements,yoga plus pilates-great if you suffering with your back. Plus you get the added benefit of a great relaxation segment which is essential for any workout. Hope this helps

I've done kick boxing for 18 months but I'm unable to pay for it at the moment, it was something I'd always wanted to do but it's time for something else and I'm running low on ideas. I'm not helping much I know lol so maybe a bit of yoga while my brain comes back to life.

what about cycling??
I know you said you haven't got a bike but maybe you could get a cheap secondhand one?? In local paper or ebay??
I have a bike and I take my backpack and get my shopping done at the same time (though I live near a park though and mainly ride it there.)
