oh ouch. so much for that whole "working out is healthy" thing right? ha ha well i think you need to get this checked out. i'd suggest making an appointment with your primary care provider. you may merely have strained a muscle but then again you could have torn one. and that would require medical attention. luckily the abdomen is protected with layer upon layer of muscle so it's not too likely you suffered say a bowel herniation or something. nonetheless if you start running a fever or vomiting or develop any other unusual symptoms you might consider heading for an urgent care. otherwise you're probably fine to just check in with your primary care provider. and of course don't do any weightlifting of any kind until you're cleared by your doc to do so. even leg work can strain your abs and you really need to rest them for now. best wishes!
was at gym. on ab crunch machine pushed too heavy weight and felt a pop in my stomach. felt like something stuck out. well i was at the gym this morning on the ab crunch machine. i leaned forward to push my normal weight and it didn't move so i pushed extra hard. and i think it was too hard. immediately after i leaned the weight forward it was followed by a bubble like feeling in my abdomen that moved upward towards my chest and i lost my breath. it felt like something popped out for a couple of seconds. this evening i'm just really sore and occasionally am getting sharp pains in my stomach.
