Would you spot someone benching with a false grip?

[IlPrincipeBrutto]

Last Saturday, as I was walking back to the changing rooms, a guy asked me to spot his bench.
I was basically the only person he could ask for this, as we were the only two people left in that part of the gym.
I had seen him a few minutes earlier, and I had noticed he was using a false grip, so I declined, telling him I don't feel ok spotting someone using the false grip.
I was quite apologetic, and he accepted my refusal without much fuss.

Out of curiosity, what would you have done?

Assuming it makes a difference, the bar was loaded with 100Kg.

That's a good policy. Everybody, please remember this post when you train today.

That's definitely what I'd do, IPB. I have a similar policy for requests for dorsal/big spoon squat spot requests, too.

I would have done the same thing.

It's even more important in Jason's example of the squat. In the bench, the only harm to you is mental. If you "hands under the pecs" spot a guy on the squat and he drops it on you, you're risking serious injury. A coach I met a while back was in a sling and I asked "why?" A girl he was spotting bailed the bar on him and it tore his distal biceps tendon.

Rip, guys,

many thanks for taking the time to reply, and also for pointing out the dangers of spotting the squat.
Thank you, much appreciated.

I would have done the same thing as you, minus the apology for refusing to enable his stupidity.
