I've read that some people have trouble with this. It hasn't been a problem for me. I'm typing at my TD now. I'm not as quick when I'm typing or mousing, but I can write code without issue. Also, much of my actual development time is spent thinking and researching and walking is great for that. For those that have more trouble, taking care of more mundane tasks (email, web research, etc.) while on the TD may make it workable. The lunchtime break is great and probably better for your actual fitness. For me, it's the 4+ hours being stationary before and after lunch that are the problem.
