I craiglisted for a kerosene heater. Picked up a little one and also have a table top dual infrared one on my work bench. The Kerosene heater is only a 16,000 btu but the heat is around 90 degrees. I come home and start both and normally wait about 30-40 minutes to go outside. I also use a little blow torch on my bar before lifting. Between those two, it normally takes the bite off enough to lift in somewhat comfort.
Anyhow, I use two space heaters but I have to make sure they are running for at least an hour before I go out. Today the temp is close to zero outside so it's probably around 20 degrees in the garage. I think the space heaters will get it up to around 30 degrees. I just layer up big time and lift quickly. It's cold enough today to where I'll probably only do one lift and the rest (assistance) indoors. 30 minutes in that is about all that I can take, but it isn't this cold most of winter.
As is obvious the behind neck press is a bitch to progress on and I don't have the best shoulders anymore so I have to be careful. Today I was frustrated and I tried them with 44lbs of chain. The chain didn't touch the ground at full extension and even though I only have 70lbs of regular weight going it was kinda fun. Ignore the quality of this photo; tinypic doesn't have an edit feature.
