You know you're a true BMFer when:

1...you know you'll only stop to recover when the class finishes

"Everyone into the plank position to recover"

"I want to see everyone doing spotty dogs while you get your breath back"

2...your instructor asks you to get into ranks or files

and then starts counting, "5...4....3...2..."

3...you understand the difference between normal time and "BMF time"

The instructor's watch is conveniently accurate when you're running late for the start of the session but as soon as the class begins every two seconds seems to equal just 1 BMF second...that's BMF time!

4...you know the hardest part is turning up.

Your BMF buddies will get you through the rest, even if they have to drag you though it!

5...you know which exercises are worth pushing yourself that little bit harder for.

6...you know how to sneak a catch up with friends

...by waiting for the instructor to walk to the other end of the file (green 34 you've been busted!)

7...you're completely puffed out, bright red with beads of sweat running down your face...

...and you're told "so that's the warm up finished, let's crack on with the main session"

8...the instructor told you 5 reps ago that you only had one more to go.

9...the instructor says, "now let's just stretch off and we're finished" and it's the best feeling!

10...you wake up the day after a tough BMF class and remember DOMS
