FEEL THE BURN!!

So my brother started coaching me in more than just boxing and wrestling. Speaking of that I haven't practiced knocking the wind out of someone but I do practice punching to that if I were to get in a fight I don't destroy my knuckles. But he made me embody the words "Feel the burn". When I stopped it wasn't because I wanted to, it's cause I had to. My shoulder was about to tear and I could feel the fibers pulling apart with a sharp pain in it. He started me off on 100, where I pushed half way up before he had to spot. His version of spotting is really different from the usual. Rather than pulling it up all the way like most people would he uses 2 fingers on each hand and pushes lightly so that it still benefits me. On 90 I did 1 unassisted and 1 assisted. With 80 I managed 5 before I needed help, 2 helped ones. 70 I got to 9. 60 I did around 12 or 13. 60 is where it got to being easy and I did about 17. Then until I reached 30 I did 20 each. Pretty good workout, my arms are still wobbly and I have a problem with holding a cup. I know that by the end of winter break my arms are going to have doubled in size. And hopefully by then I'll have a six pack to accompany it, I just need to increase the amount of cardio I do.
