I've read a few Brad Johnson articles, and linked to a couple in the past, but recently sought out all I could find. Very cool, creative stuff. Here's the rundown:

• Brad John's Extreme Bodyweight Training. Currently this link is for "See-Saw Pullups", but I assume that will change eventually as this is the start page of the series. Here's the rest:
  • Upper Body Crush Pushups
  • Sledgehammer Pull-ups
  • Ball Pull-ups
  • Anvil Horn Pull-ups
  • Suspended Renegade Rows: I tried these by tying some dumbbells to my rings. Killer core workout.
  • Gripper Pull-ups
• DragonDoor.com Bodyweight Strength Training Articles:
  • Abdominal Exercises for Total Body Mastery: It's a little hard to tell with the lighting and lack of shadows, but I believe that's a benchless Dragon Flag in the two pictures at the bottom. Quite a feat!
  • Get a Grip When You Hit the Road
  • Gymnastics Tension Exercises
  • Progressions to the Standing Evil Wheel
  • Tired of the Same Old Pull-ups? Try These!
  • The Rafter Pull-up

Back when I was doing no strength training at all, I did some poking around and found Scrapper's Workout #1. This routine will always have a special place in my heart as it, along with discovering Tabata intervals, really changed the way I train. All bodyweight exercises, no equipment required, and it's a grueling full-body workout. When I first started doing the routine, I was careful to stick to the prescribed 20-30 seconds rest maximum between sets, but I cut most of the repetitions in half, and was still wrecked by the end. I'd try to squeeze the workout in during my afternoon break from work, but by the end I was often so nauseated that I had to lie down. Even sitting at the computer was out of the question! I attribute my extreme exhaustion to three things:

1. No strength training on my part for at least 10 years prior.
2. Very little recovery time between sets.
3. Working arms, torso, core, and legs to exhaustion all in the same workout.

I really came to dread my two days per week with this workout (that's a compliment), but happily I'm much better at it now. Not so good that I'm ready for Workout #2. I may never be ready for Workout #2, but it's good to have it out there as a goal.
