Today is already the day 300 of the blog and exercise no. 300 is a pull-up variation to train the biceps and the shoulders.
I hold myself with both hands with the palms facing away but this time the right hand grabs the bar on the right side and the left one on the left side. Thus my face looks along the bar to its end. Now I start doing alternately push-ups on the left and on the right side of the bar.
