Coffee
Just like most of the lifters in these pictures power-photo runs on ridiculous amounts of coffee.
As many of you know I don't charge for photos upfront and will happily distribute them for free (Mostly) to those who ask. So I borrowed an idea I've started to see on some small software developer's sites and implement a "Buy me a coffee" button.
It will show in the gallery pages and look like the one at the bottom of this page. The link takes you to a PayPal page so it is safe & secure
