I just named my dracula training program.

First, learn to sleep on your back

Second, attach the blanket to the bottom of the bed and learn to sleep with your knees up. Use the blanket to help.

Third, put some books under the legs (on the head end)

Keep adding books until you almost slide down, get used to it and add more books.

Eventually you wake up feeling like you did a proper leg day.

Keep at it and go for isometric nucleus overload. Every 6 weeks remove half the books for 2 weeks.

You will grow enormous legs and they will stay that way.

I suppose you could tie rubber bands to your arms in stead of the books but I haven't tried that. I'm sure it will make for a memorable period of your life. ha-ha
