Don't believe us, just look at this video. This guy is having good sex and he has a six pack. There has to be a direct relationship between the two. His position sure looks like a good workout.
Look, he's keeping himself in a plank position while pistoning away at that bottom for a good 60 seconds. That some advanced bullshit you usually do with a trainer. Wait, maybe the bottom is his trainer? Anyway, try fucking a bottom like this for awhile and you'll have a flat stomach in no time. Then you'll get even more bottoms to bang and more muscles to pop. Yes, you too can fuck your way to fitness!
