Hello Mike and a warm welcome from the DiscussFitness community.
I took a look at guitars101.com once I learned that it is now part of the Social Knowledge community. It looks like a great and busy site so I'm sure you have your hands full staying on top of it as an Administrator.
Glad you have decided to jump up on the fitness saddle. Getting and maintaining superfitness is not a whole lot different that getting good at playing guitar. It takes practice, practice, and more practice, or as I like to think, training, training, and more training, today, tomorrow and each day for the rest of your life. Some days more than others, something is better than nothing.
Why don't you consider starting an
Online Journal here like so many of us have done, and chronicle your fitness training. You'll get great feedback from others and lots of encouragement and motivation to train hard and smart. Let me know if there is anything I can do to support your fitness goals.
Again, welcome aboard and have a great day!
