I've been wanting to participate in a Tough Mudder from the second I found out they existed. In fact, over the past 6 months, I had been trying to tailor my workouts to tough mudder obstacles, training the best I could for success.
I knew that many of the obstacles would take much more upper body strength than I had, so I started doing assisted pullups, rows, pushups, and pulldowns like crazy. Even with those changes, I thought it wasn't enough. I wanted to mimic tge obstacle where you pull yourself along wooden monkey bars over a river. Since I,had recently moved my runs to a park with workout equipment, I decided to start going on the monkey bars between laps.
It was working, until about the third day, when I pushed myself to do 3 lengths and I lost my grip. When I stood up, I realized that my arm was suddenly shaped differently, and off to the ER I went. It didn't seem that far a fall, but the next time I went back, I realized they are 10 feet off the ground, and I'm only 5'3".
A cast and a surgery later I find myself unable to put any weight on my arm. I didn't even get upset at the hospital until it occured to me that I woukd have to give up on it. Well, the good news is that my local Tough Mudder has not been scheduled yet, so it may be late enough in the year that I can participate. Unfortunately, I was forced to skip the Rock and Roll Half Marathon I had my heart set on.
So I have continued to train the best I can by combining lower body and core exercises with 10lb. ankle weights strapped to my arm above the fracture (it fractured at the wrist) and lots of isometrics. Hopefully soon I will be cleared to start holding weight in my hand. It is very hard to build upper body strength when you can't put weight on your arms, but I'm doing the best I can.
So that's where I am now. If anyone has gone through something similar, or has advice on training without putting weight on my wrist, please let me know!
