My exercise regimen keeps me in shape for anything I want to pursue...

Aside from commuting half-time (2000 to 3000 miles per year), year around, I do also do the following year around.
Interval training with:
1- jumprope 30 mins 1x/wk; with the intervals, this equals about 24 mins of jumping
2- kettlbells (350 - 24kg KB snatches in 25 mins) 3x/week; often I'll throw in other strength work such as suspension, body weight stuff, Akro wheels, etc.

I also run at least 1x/week @ 4 miles in ~30 mins.

Most weeks of the year, I work out all 7 days. I have enough variety that I have been able to avoid injuries associated with overtraining. Some weeks/months/years, I may do more of one thing than another, but always something intense everyday. I've been doing this for almost 9 years.

Since starting KB work ~2 yrs ago, my resting HR has dropped about 15 bpm. My understanding is that Lance Armstrong is a fan of KB training because it's so effective...
