Beth:
If you can survive PH (especially the leg portion), you'll be a whiz at S&H. This is one series you need not fear! In fact, next week I'm starting a three-week rotation on S&H after coming off PH for nine -- last 3 weeks I did it 3 times a week. I was exhausted by the end!
I almost find S&H restful in comparison. I think you'll enjoy it, too!
