You'd blend in seamless, the majority is men training solo. If that's how you feel though then you don't have to train in a gym. Gymnasts and boxers hardly use weights - the extra muscle slows em down, fatigues quickly and impacts flexibility.

Pushups, Pullups, Dips, Situps, Squats, Burpees, Running and Rope... when you get good at that buy a backpack and put weight in it.

Then crush your enemies :]
