We've asked some volunteers to participate in a very unscientific experiment.

We've given them a series of exercises.

No thanks for definite heat up.

Flexibility is not great.

Half of the exercises are uncomfortable or strenuous or awkward.

The other half are pretty easy.

All right.

How many squats?

I'm in a plank and I'm lifting my knees one at a time to my elves.

But we didn't tell people that the exercises were designed to be half easy and half hard.

It's not great.

I hope this isn't an indicator of my overall fitness.

Oh, this are so hard.

Okay.

Those are less bad. After volunteers wrapped up these activities, we asked them to

each reflect on what percentage of the exercises were difficult or annoying and what percentage

were easier straightforward. The answer should be 50% easy, 50% hard. But listen to the responses we got.

75%. It felt it was a lot harder. 25% felt easier. Maybe like a quarter of them, so like 25 to 30%, I'd say, were like easy.

I felt like I was doing the hard ones, 70%.

And the easier exercise, about 30%.

Again, we weren't asking them to rate the difficulty,

but to reflect on how many of the exercises were difficult
