Reasons to get flustered at how surprisingly difficult a task turns out to be: Helping your kid with basic algebra; getting from A to B using Google Maps; and attempting a basic single-leg deadlift without weights.

Not every booty builder needs to be a big lift with five inches of plates and plenty of grunts. Sometimes the best work you can do for your body is actually a bit simpler. Good mornings look like an easy bend, but the hip-hinge motion is actually waking up every muscle along your posterior chain.

There is an unspoken etiquette that comes into play the second you walk into a gym. Avoid irritating your fellow sweat-seekers by skipping these bad habits.

If you love to sweat or have ever trained for a big race or competition, then you’ve probably had to think about overtraining and how to avoid it.
