Hi--- I feel you and I'm glad you asked. I have been off working out other than 1-2x /wk pilates due to a back injury. I was finally allowed to return to working out and decided to reclaim my body with BBG. But like you I was concerned about my fitness level. She recommends getting your cardio up to speed if you have not worked out in a while by walking/power-walking daily for 2wks. I just did it for a week (albeit hiking for 1-1.5hrs) and also watched my food for that week before I started. I was able to finish day 1 in the amount of time allowed-- it was challenging but good. So you are aware-- I can't even run a mile!!!! But-- I hope to be able to at the end of this program:-) I'm 5'8" and of athletic build but with extra padding:-)

The best thing I've noticed about this guide is that it's completely up to you on the hardness level. If you already have the guide, go for it, and I totally recommend the pre training weeks as prep.

But as long as you are attempting the guide, and challenging yourself (whatever level that looks like) you're gonna see results! There's no need to worry if you're not getting through each circut more than twice, or super fast. That's why there's a 7 min timer. All you have to work towards is beating your own time!

I super struggled at yesterday's arms workout (barely did one time through for each circut), but I know that in two weeks I'll be doing so much better! And that's worth it.
