Yeah, I think so. You might be surprised at what you lose and it'll give you a nice boost if you don't see a number you want on the scales or something.
Question for other Level 3 people - the arm weight and leg raise thing near the end (can't remember what she calls it haha) where you're actually ON the weights on the floor - I'm really struggling, not in terms of finding the move hard, but because my weights keep sliding around on the floor and I genuinely feel like I'm going to fall and really hurt myself as I'm leaning on them really hard. When I try and move them onto the mat, the mat just slides around! It's really annoying as I want to do the move properly! Anyone got any tips?
