Thanks for the response mickc1965,
I work out in my garage w/ free weights (plates and dumbells). No lat pull down so I thought pull ups would be the next best option...?
I read this in the FAQs: "I suggest you do 2 sets per exercise during the 15s. Then do 2 sets during the first week of 10s, and 1 set during the second week of 10s. Then do 2 sets during the first week of 5s, and finish doing one set (after warm ups of course) during the last week of 5s".
I did change the second week of 15's to 1 set because I wasn't sure I would be able to get all the reps, but I'll take your advice and go for 2 sets. Should I also change the second weeks of 10's and 5's to 2 sets?
