A poping feeling in my abdomen. when i push from inside out in my abdomen, i feel a pop. what could that be? i'm a 17 year old healthy male, with no medications or health conditions. i train weightlifting 5 times a week?

Your pressing is likely to move the gas, normally present in the intestine, around and cause the sounds and feeling. It is entirely normal. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!
