Hi there,

First time poster here. I have been a competitive boxer for the past 8 years, thus my anaerobic system is well developed but I RARELY train in zone 2 on a regular basis. Once spring consolidation arrives, I spend a few months ski mountaineering on the weekends. Nothing longer than 10 hour tours.

Anyway, I believe focusing on my base for 3 or so months will be extremely beneficial come spring but I would love to box at least one day per week for 45 minutes or so. During my boxing training, I am pushing it hard for most of the workout.

My questions is: Would boxing 1 day per week (zone 3&4) be detrimental to building my base if combined with another 8ish hours working in zone 2 per week?

Thanks and any feedback would be greatly appreciated!
