>>839661There are still lots of /out/ related thing you can do. You can try the sticks, if it doesn't hurt you're probably ok. You can also try skiing, kayaking etc.
Only you can feel if its good or bad. You say you are fat but we don't know how fat you are. If you're just fat and under <30 BMI you probably be ok with sticks but if you're obese you should just stay on this and a diet until you're not.
