It would be more beneficial for you to lower the weight and get in 3-4 sets man. Remember you're going for maximum time and not weight.
I hope you enjoy hanging though! I'm on my 3rd or 4th week now and I'm still shooting for 4 sets of 3.75lbs. 20 minutes each set.
Thanks for the tip man.. I actually do do 3 sets that was just a typo. Im still only doing 3 days a week. I'm going to start doing 5 days and then try to do 7. Once I achieve that, i'll try doing 4 sets before moving onto 7.5lbs. I would go up smaller increments but I cant seem to find .5lb or 1lb weights anywhere. So I just add more sets and then once I move up, I start with 10 Mins instead of 20
