We’ve been wondering about a lot of things lately. For instance, why do our fingernails turn black when we make basil pesto? Where did all those ants in the kitchen come from? Why does it rain as soon as we get our car washed?
These are all timeless questions, of course. But today, we’d like to talk about a few exercise-related topics that have had us scratching our heads for some time. So settle down with a plate of cookies, put your feet up and watch us knock these babies down one by one.

Should I get a foam roller?

Foam rollers are these long tubes that are supposed to help you recover after a workout. The ladies above are using them after a race.

As someone who likes to push myself, but then always limps around moaning for days afterward, this sounded attractive to me.
But then I found out that the rolling part is also painful. Really painful. If you don’t dig in there, it doesn’t work.
So is it better to feel a lot of pain up front or spread out a moderate amount of pain over a few days?
That can be answered by another question:
Did you write all your term papers weeks before they were due?
If so, you should get a foam roller.

Compression gear. Should I squeeze my body into that?

Sure. Some studies say it does work, a bit.
But then others say it’s possible that it’s all in your head.
But if it’s all in your head, that’s OK. If you BELIEVE it works, it works.

Do I need that $200 sneaker?

If there’s one thing I’m a sucker for, it’s a shoe that fits. (Still waiting for that, hiking boot makers.) So I have been running in Asics for years. They cost a bit, but they make my feet happy.
And some feel that in running, a comfortable shoe is more important that wearing an expensive shoe.
If you’re new to running, get yourself over to a running shop and talk to the employees about the right shoe for you. You will be shown shoes in a range of prices, which may go up to $200. You could buy that shoe. But you don’t have to.

Find something that is comfortable and works for you, and if they do, it doesn’t matter if they are twenty quid or a hundred and twenty quid. — Roger Kerry, Associate Professor in the School of Physiotherapy at the University of Nottingham
