Does the "Conditioning" perk improve sneak and stamina?

I have a warrior/mage build, and I am specializing in heavy armor. I'm doing this because I tend to die easy and light armor doesn't sound like enough protection (despite what others say).

I was wondering: if I get the Conditioning perk, will this help with my sneak and stamina?

Solution 1:

70 heavy armor (required for Conditioning) is a long way away. What you really want to solve the sneaking issue is the Muffled Movement perk at 30 sneak (50% noise from armor) and the Muffle spell from illusion.

The survival issue is simple - don't dual wield. Add a shield and you will live. Blocking is a huge damage reduction, but even when you don't block the shield adds armor!

Stamina isn't a big deal if you spend a handful of level ups on it and get the Restoration(40) perk - Respite (Healing spells also restore stamina).

Solution 2:

It will help your stamina, thats for sure. I've got the perk and I can run for a long time without getting exhausted, before the perk I could only sprint for a few seconds. As for sneaking Im not sure, since my sneaking is only level 30. I get caught easily but I do so too with light armor and sneak bonusses.

Solution 3:

Yes. The stamina effect of armor is based on its weight, so getting conditioning will mean that your stamina decreases much slower while sprinting.

Sneak impact of armor is based on two things, weight and noise. So getting conditioning will definitely help by reducing the weight. From there, you will want to get Muffle as mentioned by David to make your armor even stealthier.
