5 Weight-Machine Exercises You Should Never Do


We have our reasons for picking each of these exercises, but with each one you’re just not getting the most bang for your buck when you use exercise machines. Why? For one, you usually end up not using the muscles you want to be targeting as much as you think, because your more dominant, stronger muscles end up doing most of the work. Two, these machines end up doing 30-40% of the work for you, robbing you of your progress! Try these alternatives to engage multiple muscle groups at once, force yourself to engage your core, and make your workout as efficient as possible.

1. Crunches. An improper crunch is the best way to strain your neck and totally ignore your abs. Many people pull from their neck and then curl up in a way that puts needless strain on key points of their spine. And using an exercise machine is no guarantee that you will be doing it correctly.

Try instead: Planks. Get in a push-up position, propping yourself up on your elbows and forearms. Holding yourself up while keeping your back, butt and heels in line with each other works your entire core, without any of the strain of crunches. With planks, you’re working your entire core, making it more effective than a crunch. Try holding the plank position 3 times for 30 seconds each.

2. Thigh Adductor Machine. If you’re fixated on your thighs and think the adductor will help them spot reduce, think again. Here the machine is doing a lot of the work for you and you’ll get much more out of it by doing something else. Without the machine you can work on the thighs you’re after, and you just may be able to reduce knee pain at the same time.

Try instead: Squeeze bridge. Get on your back, feet on the ground and knees bent, holding yourself up so your body is at a 45 degree angle, and hold a yoga block between your knees. You’ll feel your core and your inner thighs burning. If you don’t have a yoga block, try a rectangular tupperware container – just holding it there will do the trick for beginners.

3. Ab Rotation Machine. While you may think twisting your torso on the ab rotator is the way to target obliques, you’ll find that your dominant muscles in your arms and shoulders end up stealing the benefit from your abs. You get all the bad form of twisting your spine, and none of the oblique benefits.

Try instead: Standing side crunch. Stand with your feet wide and hold a weight in each hand. Hold your left weight in front of your chest. You’ll want to lift your right knee and your right arm at the same time, as shown, balancing on your left leg, using your core to stabilize yourself. Return to standing and switch sides. Also, check out moves like the bicycle crunch for an ab workout without the machines.
