<human>: Summarize the given text in a few sentences.

OK here's my plan,

So basically, I've had a bad case of the flu for the past week, and in doing so, have done no exercise, I'm a very fit 21 year old male, I rock climb a lot and my general motto on fitness is to be as fit as humanely possible for the activities I do.

What I want to try for this week is the following:

I will be training every day, give me hard out ridiculous challenges to complete. Think of some ridiculous work out or circuit and I'll write down all the ones I feel are not insane and do them this week to get back into the swing of things. Rest days will be me in the climbing gym, most likely Tuesday and Thursday. 

I don't know if this will work, depends how many people want to get behind it.
<bot>: Give me the most intense exercise or circuit you can think of. I'm very fit and have had a week off.
