The high-rep days are hard - almost killers. They show your character
.
They work. I've seen big steady gains. That's why I'm here. That keeps me motivated. Alwyn writes the plan and I do the work. The goal is bigger than the pain, and I always feel better when I walk out of the gym than when I went in.
When I track PRs, I compare with the same workout from the time before. I compare 15-rep days with the same previous 15-rep day. Don't get discouraged because the weights are lower than your 5-rep or 10-rep days.
