When it comes to staying in shape, most of us tend to have shiny object syndrome.

Unfortunately for us, the next big thing could be ineffective or even dangerous.

These are the exercises your personal trainer hates.

There is a reason that people take years to learn these moves.

They are tough!"

Spraul also told me that dumbbells and kettlebells can get you just as fit.

“There is a lot more room for error without the high risk of injury.”

Full sit ups

If you want abs, sit-ups seem like a good place to start.

However, just about every personal trainer I spoke with hated them.

It’s a killer!"

“The abdominal muscles that sit ups are supposed to work are activated eccentrically.

This means that they work when you are slowly stopping yourself from moving.

“Slowing that descend down would make it a more effective exercise.

A better replacement exercise to work the abdominals would be a leg raise.”

Woodchops involve swinging your arms across the body and using your core to stabilize.

“You will usually see people holding a medicine ball and going diagonally across the body.

If you notice pain, it’s important to stop, rather than pushing through it.

“There are two popular exercises that make me wince every time I see them.

This can lead to impingement and rotator cuff issues.”

Any move that forces you to twist or rotate your shoulders too much is dangerous.

Barbell upright rows

It seems that barbells couldn’t get a break with these personal trainers.

The risk for injury is higher, so most recommended changing up your equipment.

“Do dumbbell front raises instead.”

Abductor/adductor machines

In addition to safety, another factor the personal trainers kept in mind was effectiveness.

Just because an exercise is safe does not mean it’s worth it.

Many of us like to focus on one or two trouble spots when we’re working out.

Overdoing it on the leg machines is a common mistake among female exercisers.

“Do walking side lunges with a resistance band instead.”

“Abdominal crunching is not nearly as effective as using your core as a stabilizer for the body.

Burpees

I’m not going to lie.

I was pretty excited to hear that burpees can be dangerous.

“Burpees can be dangerous.

“In exchange for burpees, I recommendget-upsfor functionality.

For a cardio burst, add five rounds of tenkettlebell swings.”

So unfortunately, these moves definitely don’t look easier, but at least they’re safer.

Instead of going straight for the machines every time, wander around the free weights area.

“Pilates is a good workout if you want to strengthen your core.

However, a Pilates workout doesn’t burn very many calories,” warned Buckley.

It’s just not the best use of your workout time if weight loss is your end goal.”

However, just doing cardio probably won’t help you hit your weight loss goals.

“Longer isn’t always better.

I’ve certainly done that.

However, try not to make a habit of it.

“Unfortunately this exercise will not bring about any desired results and is a waste of time.”

If you’ve always been a treadmill walker, start by including some intervals.

“I highly recommend doing intervals, altering either the incline of the treadmill or the speed.

“This is what will burn fat and tone at the same time.

BOSU ball exercises

BOSU ballstend to be a favorite among personal trainers.

So I was surprised to hear that not all personal trainers love them.

“Abdominal-focused strength machines that focus on rotation are the most dangerous movement,” explained Shapiro.

Instead, Shapiro recommends backing off on the weight used.

“I would prefer a slow standing cable rotation using minimal weight,” he said.

“Standing compared to seated movements already uses more caloric expenditure and core activation.

It’s meant to work chest and triceps.”

Article image

Instead, focus on full body exercises that also target the triceps.

Perhaps a cirque du soleil person might do them or someone in the military.”

So in other words, just skip them.

Unfortunately, that may not be the case.

“I just think they’re useless.

They are supposed to be great for toning your backside, but put your low back at risk.

However, even when it comes to effective workouts, they can’t stay impartial.

“I hate bear crawls,” Balance Gym personal trainer Ben Wiedemer told theWashingtonian.

Wiedemer shared that bear crawls were always his least favorite, and now he never does them.

Next time you’re working out with your personal trainer, ask her what exercises she hates.

Even fit personal trainers are human!
