I am going to be able to XC ski in my holidays so will probably to that, both classic style and freestyle (different muscle groups and technique) However, I will ease into it, not over do and get plenty of rest so its not a total shock to the body like earlier this winter
I used to travel a lot for work and I found a great app called 7 Minutes. Has some variety. It’s basically 12 high intensity bodyweight exercises for 30 sec each, with a few seconds between each. Looks like Wahoo bought them, so not sure what changes took place. I’d keep a small travel bag of some things like jump rope, bands, etc, but you don’t need them for this app.
