You will be fine I think! I don't have a lot of upper body strength at all and I was able to make it through every obstacle, even if it took me a few tries lol. Just make sure you eat a good, nutritious breakfast because I have a friend who went with us who had been on a pretty low calorie diet and she didn't eat much before hand and she ended up in the emergency tents because she got dizzy and felt like she was going to pass out.
