We don't have 'punishments', which may sound odd coming from a military club, if you are lazy and don't train properly the only one who dips out is you. You lose the respect of the others and that hurts more than any press up or 'punishment' an instructor can give. Not seen it happen because those that come to the club ( it's a hobby/sport for them albeit one encouraged by the senior officers) want to enjoy training and have enough self discipline to train properly albeit with a lot of banter civvies would find odd.
