There are a few favorite places on the web that I should share. Some are sites that I frequent and some are sites that I owe homage to for their place in my fitness journey.
#1 has to be http://www.fitday.com/ . Hands down, there is no other way for me to maintain or lose weight other than calorie counting. If I eat 2000 calories a day, I will lose 1 pound per week. If I don't count, I eat 3000 + per day and eventually it catches up.
In the beginning there was http://www.mattfurey.com/ . I love the spirit of Matt's workouts. There are no weights. It's all bodyweight excersizes. For working out alone and without videos, his stuff is great. I love that he hates LSD (long slow distance running) and favors hill sprints.
From there I graduated to P90x. http://www.beachbody.com/ I have booked around 4 years and hundreds of hours on my P90x DVDs. The P90x2 DVDs are in the mail. And don't forget Insanity... always a pleasure.
Lately, my friends (pretty much Mike) has grown tired of P90x and is a big fan of http://www.crossfit.com/ . I'm a fan too, but I don't like the clean and jerks, squats, and general body-building workouts. I like the grind it out workouts. The do this 10 times, do that 20 times, do this 30 times.... repeat 10 times kind of workouts. I like the do this 100 times for time workouts.
Thus, all of these sites, books, dvds, have contributed to my view of fitness and diet. I will add more in the future, but this is a great place to start.
