You don't have to be of any particular standard to start TKD. The training will make you fit. The more you train, the fitter you get. It's all about going at your own pace and reaching your own goals, not someone elses.

Go to the frequentlly asked questions part at http://www.tagb.biz if you have any questions. If in doubt, speak to your local TKD instructor.

The hybrids, aka fitness bikes/urban bikes are basically a mixture of MTB and road bikes. They are using the geometry of MTB but the concepts/ideals of a road bike. The wheels on a hybrid are 700 cc which is similar to a road bike but the tire size is actually a little bit wider and thicker. (instead of 18-25, it is 32-38). The riding position is similar to that of a MTB with a little more relaxed feeling and not an attack position. The components actually go both ways. Some models have MTB components while some have Road bike components. That depends, however, on how high of a model you get. Some, also have carbon fiber distributed throughout the frame/fork while others are fully rigid. Sometimes you'll find a suspension seatpost but on "fitness" bikes it is usually a rigid fork. Weight wise, the hybrids range from 20-25lbs but are actually surprisingly fast. Trek, Giant, Specialized, Cannondale and a couple others all offer hybrids now.
Pros: hybrids are cheaper and have the same basic concept of getting from point A to point B quickly but comfortably but still a nice ride to work out with. The geometry is very similar to a MTB. Faster than MTB. Not much maintenance required if you take care of it.

Cons: Not as light as a road bike. Components can be cheapy if not purchasing a good model. Can be as expensive as road bikes if purchasing a good model.

I have both MTB's and Road bikes and I love both. I just love to ride regardless of what bike it is. However, there is a HUGE difference between the two. If you just want to get from point A to point B, I say get a hybrid. If you want a cardio work out and get HUGE legs, get a road bike. It took me a while to break down and buy a road bike. I owned only MTBs for years but decided to finally give it a shot after starting to work at a bike shop. I like both but nothing beats MTBs. Go to a dealer and try them both out, hybrids and road bikes. Ride it for a while and see if you can see yourself getting comfortable on a road bike. If not, your choice is pretty much made up. If so… well…. questions… questions… questions… and price… price…price. Good luck mate.

Askmen.com also rates chocolate milk as the #1 recovery food, if taken soon after the conclusion of the workout.

As for me, I stick to a homemade shake with water and soy milk, protein powder, fruit, raw cocoa, brewer's yeast, and flax meal.
