Adjusting Alternator Belt

[MILD]

Try as hard as I can and still can't get the correct belt tension!

Is there a trick to getting this or is it a two man job because of my muppet arms ? At present I'm pushing it as hard as I can and then holding it in place with one hand whilst tightening it all up but I'm just not getting the desired result. Anyone got any advice or should I just call a mate to give me a bit of extra strength- I've only got to get another couple of mils of movement!

Please disregard: I used another tool for leverage and got it done that way... thanks for reading though!
