Definately try with your arm at your side. I think having your hand out in front counter-balances you in a way and decreases the effectiveness of the drill. Make sure not to flatten out though, you still want that body roll that puts you on your side with each stroke. I have found that triathletes especially HATE to take their time with a drill and rush through it trying to "do work" You really have to take your time on this drill or you wil either sink or be very tired after a 25.

Good luck!

Wow, thank you for sharing. I hope sharing this will help ease the recovery a bit. I am so sorry what you and your family went through. Don't ever think it was 'because' you went to Hawaii...regardless, there is a reason for everything. Your wife is a special person. Congrats on an awesome race in Hawaii!
