Hello everyone i have a question about the greyskull lp program that i'm thinking about starting today.

I have two variants that im deciding to do; A: http://imgur.com/4zQdb or B: http://www.powerliftingtowin.com/wp-content/uploads/2014/04/greyskull-lp-arms-plugin.jpg

Im leaning more towards hypertrophy rather than strength. But my main question is what do they mean by (alternating) its a bit confusing do i do Mon:bench, Wed:Press, Fri: Bench and for week 2 switch them around? If someone has a suggestion i would appreciate your feedback also for those who have done this program what are your thoughts and results? Thanks.
