Just doing some strength-training exercises means that you’ll get fit, lose weight, and be a better runner, right? Not exactly. Not every move or machine at the gym is going to make you stronger or fitter. Some are not that helpful at all, no matter how many reps you do. Here are nine moves that simply waste your time, and nine moves you should do instead.
1/ Seated thigh machine (adductor or abductor machines)
Why it's a waste: It seems like it will help you get rid of the fat on your inner and outer thighs, but it won’t. “Spot reducing” exercises don’t help you lose fat.

These exercises tone and strengthen your whole body, including your thighs, says Greg Justice, an exercise physiologist at AYC Health and Fitness in Kansas City. “Plus, they are functional, which means they train the body for activities performed in everyday life - something the thigh machine does not do.”
2/ Leg extension machine
Why it's a waste: “The stated goal of this machine is to strengthen your quads, but you actually end up just putting a lot of stress on your knees as you straighten your legs from the seated position,” explains Justice.

3/ Crunches
Why it's a waste: They just aren’t that effective. “Research has shown that the crunch is less effective at stimulating muscle fibre than exercises that require the spine to stabilise, like the plank.”

4/ Barbell side bends or rotations
Why it's a waste: While you may think you’re strengthening your core or burning fat, you’re not. “There’s really no resistance when you put a bar weight behind the neck and start twisting or bending. It’s much better to work against gravity,” says Justice.

5/ Seated chest presses
Why it's a waste: “You’re sitting down, which allows the stronger side of your body to compensate for the weaker side, which means you’ll develop imbalances,” explains Barnes.

6/ Lying leg curl machine
Why it's a waste: Lying down to exercise means that your core is not engaged, and you activate the least amount of muscle, says Barnes. “When in real life are you ever lying down curling your legs to your butt for any real purpose?” he says.

But best of all, “this exercise gives us the strength we need for bending and the balance we need for real life single-leg activities, like climbing stairs, stepping on a curb, or lunging down to pick something up.
7/ Triceps kickbacks
Why it's a waste: “You won’t be able to lift weights that are heavy enough while keeping proper form, to get results,” says Justince. “Usually, the upper arm starts to drop toward the floor and you lose the effectiveness.”

8/ Standing calf raise machine
Why it's a waste: The machine loads all of the weight onto your shoulders, which pushes it onto your back before it ever reaches your calves.

That’s because it activates more of those fast twitch muscle fibres responsible for strength and growth development, which leads to a more toned body overall,” says Barnes. If sprinting is not for you, try bodyweight calf raises, and if those are too easy, then try them on a single leg.
9/ Leg press machine
Why it's a waste: “People tend to add too much weight, which adds potential for injury,” says Justice. Plus, it’s not that effective: A study by the American Council on Exercise (ACE) compared eight different exercises that target your glutes, and found that the leg press activated the fewest amount of muscles.
