I always thought Thai Kickboxing was the manliest. In terms of dedication involved and skill + brute force; football (of any kind) has nothing on it. Im a regular kickboxer myself but would take Muay Thai if the studio wasnt so far away.

Heres a few doses of manly wupass. Id take a tackle over a knee to the face every day.

Some history behind the sport. Spanning hundreds of years, again football of either kind has nothing on it.
