Anyone who has spent time at a gym has seen it. A man attempting to go beyond his limits to improve his answer to the question "How much do you bench?"

Working out with too much weight for ego purposes isn't smart.

Sometimes it becomes comical. Friends shout encouragement as the man struggles with the weight, veins pops out in his neck, and he thrusts his hips off the workout bench to help his overmatched chest muscles.

Ken Karnack, a personal trainer for 12 years, has seen that many times.

"They yank their hips up off the bench over a foot and they're screaming and yelling," said Karnack, the owner of Old School Fitness in Frisco, Texas.

"With men, their ego tends to take over and they think they can do much more than they can."

Ego-pumping is responsible for many of the ridiculous things men do when working out.

Here are six of those, as well as some advice from fitness pros to keep you from standing out — in a bad way — on your next visit to the gym.

TOO MUCH, DUMBBELL

Yes, this one really is about the ego.

Dumbbells or barbells, machines or free weights, many men go for too much. That can lead to bad form, which will not train muscles properly and can lead to injury.

"The last two reps of a set should be challenging," said Shannon Edwards, a trainer at Cooper Fitness Center in Dallas. "But you should never compromise your range of motion."

From first rep to last, you should be able to control the weight.

SLAMMING, GRUNTING

Slamming down the weights is very manly. Some guys think so, anyway.

"Men in particular love to do this because they think it draws people's attention to them and how much they are actually lifting," said Matthew Heinrich, head of personal training at Lifetime Fitness in Garland, Texas. "The slamming of weights can be very annoying to the people around and all they are really doing is damaging the equipment."

Another look-at-me strategy is the weight-lifting grunt. Maybe it helps some guys complete a lift, but probably not.

"No science has ever proven that the louder you grunt, the more you lift," Edwards said.

If grunting or slamming weights down is not intended to attract attention, it's probably a sign of attempting too much weight.

LIMPY LEGS

Some trainers call these guys "lollipops."

Others say they look like big light bulbs.

They're men who build their upper bodies but neglect their leg muscles.

"Guys tend to train the 'mirror muscles,' " said Israel Allen, a trainer at 24 Hour Fitness in Southlake, Texas. "And most guys won't look at a full-length mirror. That's a woman thing."

All parts of the body should be trained.

Trainers also encourage a balance of pushing exercises, which men favor, and pulling exercises.

LACK OF COURTESY

A woman could be to blame for the sweat puddle around the treadmill or the damp seat on the stationary bike. But men are more likely to commit a breach of gym etiquette.

"Cleanliness is not one of the priorities of most guys," Allen said. "We need to get better at that."

Wiping up sweat is one courtesy.

Another is being conscious of body odor and using deodorant. Wearing appropriate clothing is also important.

"I'm not a big fan of the Spandex bottoms without shorts over them," Edwards said.

No more explanation needed.

TRYING TO GET A DATE

While some men are working out at gyms, others are scoping out potential dates.

The notorious gawking at women is one reason that gyms specifically for women are popular.

What do these pickup artists think of the gym?

"It's a bar without beer," Edwards said.

It's also rude.

And for the guys flexing in front of the mirrors as the women walk by, a reminder from Karnack:

"You can't flex fat."

UNTRAINED TRAINING

A lot has changed in the last 20 years, but for some men, the gym workout has not.

That's partly because men don't like to ask for directions, whether they are on a road trip or a path to fitness.

"Men don't want help because they feel they know what they are doing," Heinrich said.

"If they truly understood the body and used a trainer for even a short period of time, I believe they could increase results and get past the same plateaus their current routine has created."

That might also keep men from passing along bad fitness advice to others.

Some men not only stick to the workout they did when they were playing high school football 20 years ago, they expect it to work for everyone else.

It's funny, Heinrich said, when he sees a guy teaching the workout to his wife or girlfriend.

"Because we all know that her main goal is to break tackles and run a 40 faster than all the other women," he said.
