Welcome to Gaia! ::

I'm not too good at it, but I generally keep some kind of activity in my weekly schedule because a lot of the things I like to do are physical activity. For work outs, that's harder... I'm not as good at that.

Mostly, I know I have more energy in the morning. When I decide to do a work out, I generally have to get right on it otherwise I lose interest.

Find a way to hold yourself accountable. Perhaps join a group that does things in your area. I'm involved in a fire troupe, (I do stilting) so I have to practice somewhat during the week so that I can show improvement for my troupe leader.

You could check and see if there are SCA (Society for Creative Anachronism) meets in your area, they often have loaner armour and groups often meet for fights weekly. It's a little geeky, but such great exercise.

Heh. I thought you'd be interested. The SCA is a group of people who are generally pretty serious about their historical accuracy, but they're pretty fun. At least my local group is. Check this out and see if there's a contact for your area. http://www.sca.org/geography/

This guy's obviously being an a** hat, but that's the calibre of activity that can happen in a fight. (And this kind of behaviour isn't usually tolerated like that. In my local group the people there would be doing mean things to someone who acted like that.)

Basically it's moving quickly with anywhere from 15-30 lbs of armour on. Swords are usually made of Rattan wood wrapped in duct tape, and shields are more often than not wood with bike tires wrapped around the edges.

It's pretty cool, and you can meet some amazing people.

There's lots in the states, http://www.sca.org/geography/

Go there to find out, (you'll have to scroll down a bit)
