Training alone sucks.

Today I was on my last day of HST, heavy 5s.
Did my 1st inclien DB set with 40s, was easy so decided to go for 42.
Got them and my knees and as I rolled up I lost my focus for a split second and couldn't get them up.

I knew this wasn't going to work, waited for 30 seconds with them on my knees and tried again but there was no hope.
I dropped them and asked someone to spot me and help me get the 1st one up. He looks at me with disbelief and says "whoa, how many?" I told him that I should be able to do 5 on my own, just need help getting them up.
So anyway, got the 1st one up with probably a lot of help and then it happened.
I did 10 clean reps on my own!

He didn't even touch my arms through the set, I just kept banging them. I'm definately not lifting as much as I would with a proper training partner.
