I know a guy who can do 12 minutes... I had time to have a chat with a mutual friend, go get changed, come back to finish off the chat and he was still going. As if that wasn't bad enough, he justified his motivation as needing to beat his friend's mum who can do 16 minutes. Makes me sick.
I think the most I've ever managed when I was doing regular ab+core work was 3 or 3:30 but looks like I'll just have to start training again so I can get my name in at least one of these Vegan Fitness tables... And the pushup challenge is so not happening here so I don't really have a choice
