FB Mass

Having been in my best shape when strength training in the gym and now no longer being able to face leaving the house after I get home from work with the dark Scottish winter well and truly here, I've returned to fitness blender after a few years. Tried FB Sweat but I much prefer strength training so I finally got myself powerblock dumbbells and am on day 2 of FB Mass.

So far so sweaty! Is anyone else doing this plan just now or done it before?
