Did you work 14 hours today? Is it dark and rainy out?
Go into your garage and hop on your RipRow™.
Crank out 3 minutes x 10 sets.
That adds up to about 800 reps, today focusing on the moment in a bunny hop when you start to pull the bars.
Make it smooth ... then make it powerful. 30 minutes at threshold effort and a full-body workout -- plus you got better at mountain biking.
Done. Now hang out with your wife. She'll appreciate how mellow you are.
