20 Rope Climbs 15' for time Workout

20 rope climbs for time (15')
about 12:15
I did this and felt o.k. but not overly warm before going. I taped all fingers well and that was a good thing.
I was trying to really concentrate on pulling my knees up high to really use my legs as much as possible. I was trying to do 2 pretty close together on the minute, but by my 4th round of 2s I was already feeling it to be honest.
My grip was a bit tired and forearms. I was trying not so much to pull with my arms, as to grip the rope hard and then pull myself and knees up to regrip the rope with my legs and drive up that way.
Good workout. I was tired but needed to stretch out a bit and then I went upstairs to stretch and then to do the 50 calestetics movement new WOD upstairs, called "Marguerita"
