Never underestimate the value of training the basics, no matter the field or activity you're into. Your fundamentals are called that because that's precisely what they are. Don't just go back to them once in a while. See the basics in all things, no matter how advanced you are.
I am now offering personal training at the Lake City Fitness Center. If you would like to learn all about bodyweight training, please get in touch! I can design a program for any experience level, from beginner to elite athlete. Even if you have a tight schedule, we can try to get in short but intense workouts that will still push you to your limit and burn off the calories!
In the video below, I demonstrate a calisthenics progression for Dragon flag, a technical, difficult, and cool looking movement credited to Bruce Lee. Rocky Balboa also used the Dragon flag as part of training for his fight with Ivan Drago in Rocky IV. Dragon flag works most (if not all) of the torso, as well as the hips and glutes. In my opinion, the Dragon flag most difficult bodyweight training exercise for the abdominals that I can think of.
Want to get in great shape without having to buy any equipment? How about having fun learning cool new skills? Calisthenics classes are just what you need! The focus is purely on natural bodyweight-only movements - you are your own gym! There is no strict age limit - families are welcome and encouraged.
