Calendar/ programs and ability to adjust


I am going to buy one of your programs. I haven’t bought a program in a long time ( actually probably about 3 years + ago). I sometimes have to miss a day. Is it possible to move the days forward in the calendar or how does that work?Also,I can’t see the program I bought in the distant past when I log in. Do you know how I would find that or if it is still available?

Thanks, robyn

Ps just love these workouts. I used to pay 75$ an hour to a personal trainer for the exact same thing.
