Can i start bodybuilding

oh no, i would leave the back exercises alone if you have back problems as the back is the weakest muscle in the body. i would get exercise recommendation from a doctor if you don't have a straight back if he recommends them. i think it would be okay for you to do bodybuilding exercises that doesn't put pressure on the back suck as sitting dumbbell curls. the reason i say and like the dumbbells weights is because they provide a better range of motion that can work the biceps better. also the bench press would be ok since your laying on your back while do them. i would recommend a barbell for bench pressing since it would be easier to get a grip on and handle the heavier weight while lifting and also because its a compound exercise that works many muscles such as the chest,shoulders, and triceps. also you could do an exercise for your forearms and wrists that involves hand squeezing exercises. the hand squeezing exercise piece of equipment i use is the ivanko super-gripper that can develop very strong forearms and wrists because it has so many levels of tension you can work up to. all you have to do is adjust the 2 springs of the ivanko super-gripper in order to increase the amount of resistance of the super-gripper. the amount of tension the ivanko super-gripper can you goes up to around 345lbs which is extremely difficult to achieve. if you want to be safe your limited to the amount of exercises you can do if you want to avoid putting unnecessary or dangerous tension on your back. i'm not a doctor so such a doctor could inform you better on whats safe and not based on seeing your condition.
