it depends on you really, coz i had biggish implants but small boobs to beging with, it took longer for mine to settle and my skin to stretch, i waited till i was a few months po till i worked my chest, id say do small exercises and work you way up, may be 3 diffrent chest exercises for 5 then repeat this for 2 sets, then work your way up till your doing say 12 or each exersise for 3 sets hope that makes sense lol xx
