What type of Energy system work would you suggest for those of us who live in the cold winter of Canada? Outdoor sprints are not an option for me right now, and I don’t have access to an indoor track - just regular cardio equipment. Thanks for any info!
If you have access to stairs you can always to stairs sprints. HIIT on the treadmill is alos an option. Not as good as the real deal but given the circumstances it’s better than nothing.
We got 8 inches of snow in the last 12 hours so shoveling comes to mind! :0)
