man i must be hella-spoiled then! we have central A/C and heat in the building i train in so it's always a decent temp. personally i have never used the A/C anyway but i dont like training in the cold, makes for creaky joints!!!
baby that shoulder HH, the last thing you want is an injury in that area!
i'm with you HH in that squats are never gonna feel comfy when you're pushing yourself with them. but it's all good cuz that's how ya get the big wheels
