Remember muscle is twice as heavy as fat. My advice is drop the weights and take up a bit of swimming or surfing for upper body tone.
I took my 10yo swimming at Mingara this afternoon. He isn't as fit as he should be at his age. I could easily swim 2km in primary school, but he can't swim 50m without changing strokes to catch his breath. I thought I could use the training too, so we both went to do some laps.
Anyway, to my horror, I discovered that I can't swim 50m without catching my breath either ! I was shocked.
What this has shown me is that while my legs are coping easily with the cycling, my lung capacity or cardiovascular fitness is FAR worse than I thought.
I plan to visit the pool a lot over the next few weeks. I might be a lot further away from getting back into racing than I thought.
Thanks for the suggestion, Matt.
