Training 2x times a day VS 6 days a week.

Hello guys,

Just wanna hear some opinions, I currently do 4x Crossfit class a week with Thursday & Sunday off.

I feel good to add some other 2x training that I like (running, cycling, swimming)

Would it be better for my body to train 6 days a week

Or

Do 2 training on 2 days a week like Tuesday and Friday on medium intensity with 2 days off.

Gotta admit I like 2 days off, just not sure which one would benefits on performance and also recovery.
