Sports challenges: keep it low (squats)

So, as I mentioned before, I've been trying quite hard to get fitter and improve my physical state, or, in other words, to get ready for the summer. I have found a lot of tips and tricks on the internet, which also involved different kinds of sports challenges. So, I found a series of those monthly challenges. They contain only one kind of exercise, but as you move on with it, you have to do more and more of it. So, although it's recommended to take only one of them at a time, I started off with two, and I am going to comment gradually on how I am doing with both of them. The one I begin with is the monthly squat challenge. I have been squatting for 13 days now, and I really feel it's getting very difficult. It's been 130 squats in one go for today. Quite a workout actually.
