I'd like this workout to be 60 minutes long. I would prefer if it contained some core work, even if it cuts into the floor work. No big deal though - I can always pop in another video.
I would love to see some exercises that you can go heavy on without needing a spotter or a rack. Bent-leg deadlifts come to mind. I also love step-ups. Also, balancing exercises, such as one-leg dumbbell squats with the non-working leg not touching the floor would be really challenging.
I really like the straight-leg deadlifts that you usually include, but I'd also like to see some kind of leg curl, if possible. I guess that's pretty tough to do without a machine.
I'd prefer more of a balance between quads and hamstrings, rather than so much quad focus as usual. Also, I agree with everyone that some *tough* calf work is in order!
