Post cardio shake?


New member
Hi, I was wondering is it absolutely necessary to consume the protein shake after cardio?

As after i finish my cardio (In the gym), I tend to go spend 10-20 mins in the sauna and finish with a shower.

Is it ok, to have a protein shake made overnight and store in in hte freezer in a bottle?

Wil lhtis affect the shake's quality?
i take a shake in after i work out too not get catabolism. I take in whey protein shake about 50 grams of protein.
I dont know about the protein shake over night I would say u can b.c i don't see how it would degenerate.
