Question: how many calories does the average gym session burn?
Answer: In 30 minutes, the average person burns between 240(125lbs person)–355 calories(185lbs person). If you hit the weights, you probably burn 90 (125lbs person)–133 (185lbs person) calories in each 30-minute floor session. But one needs to remember that the more muscle you build, the more energy your body burns at rest.
