hey Bolddaddy!
You are correct, in why they switch the schedule around a bit. It is really just a way to alternate the workouts up to keep you motivated and interested. As long as you are putting in the work, that is all that matters. Keep pushing!
I have a support and accountability group and we would love to have you participate with us. I have done a few hybrids, as well.
Come on over and post with us.
