Why can't you practice?
Can you ride a stationary bike?
Can you swimn?
How did you get so 'heavy' in the first place?
Practice proactive rather than re-active. Or, said another way, once you got your weight down, keep it down!
I was 8 pounds over once. Cut the weight and then was so weak I got by butt kicked by a kid that was not better than me. However, it was a good learning experience. I NEVER let that problem happen again.
Stay away from the pudding!

When is weigh-ins for you?
