... I lift 5 or 6 days a week but really if you can get 3 or 4 a week that’s all you need if you are doing other physical activities around the weights. ...
I do some pretty chill strength training 2 days a week and it's been transformational for the rest of my activities. I've never felt so good on skis in my life (from a fitness perspective, not a technique perspective ). It did take probably a year+ of that to really see the results but now that I've built up some decent strength it's easier to maintain. I'm sure if you do more days a week you see results faster, or more dramatic results, but if you're just looking for day-to-day functional fitness and feeling good 2 days a week seems to be fine.
