1LRDL

One-Legged Romanian Deadlifts (1-leg RDLs or 1LRDLs or OLRDLs)
These require good balance. Falling over isn't something you should be embarrassed about. You may need to steady yourself against a wall or couch when you first start doing these. As you get better, you can continue to challenge yourself by standing on a pillow or other thick pad, with the idea of destabilizing your balance, making you work harder to stay in place and in that way increasing your ability to balance.

Tip: Slow and controlled is better than quick on these, at least at first!

Question: How can I improve my balance so I can do 1LRDL's better? (Discussed here, here)
 * Do the King of the Klutz exercise described in the YAYOG book.
 * Practice a few yoga poses: tree pose, half moon pose, and warrior 3 pose. Practice moving your arms in lots of different directions in all those poses to help improve balance and concentration.
 * Focus on a point in front of me when doing the 1LRDLs.

Question: What is one rep for this exercise?
 * "I actually helped DickTalens put this exercise into the Fitocracy database, so I can tell you that the exercise *originally* was set up so that you should log 4x your actual reps for Fitocracy. When I say "4x your actual reps", I'm assuming that you count one rep as going up and down twice for each leg" (ref).
 * Essentially, that means you count each time you touch the floor as a rep. The focus of the exercise is on the deadlift itself, and one-legging it is just a way to up the difficulty. You're getting one rep per deadlift, rather than per side (ref). Thus, when doing ladders of these, your rep progression will look like 4, 8, 12, 16, etc.
 * Another option is to log one rep every other time you touch the floor. The logic is that it's like any other exercise -- you do a left-leg and a right-leg before counting one rep.
 * Another option is to log one rep after touching the floor four times. You need to touch the floor four times to get all combinations of left/right hands/feet, and that's what the YAYOG book calls a rep.
