(Pyramids to keep it interesting)
Set up a “new workout” on your rowing machine to Intervals> Distance: Variable.
Set up intervals of 5,000, 4,000, 3,000, 2,000 and 1,000 meters, with “unlimited rest” between each.
Between each interval:
- Ski 500 meters
- Optional: 25 situps and 10 pushups
Adjust the number of intervals and the distance of each to meet your meter target.
