New Exercise Equipment

This article describes the pros and cons of various kinds of  new exercise equipment used for strength training – bodyweight , weight machines, free weights, exercise bands, etc. Each has its benefits, and you should experiment to find what works for you.

Bodyweight Exercise

Pros: Free, Always available, Natural movements/> Cons: Harder to increase difficulty incrementally, Requires a bit more creativity

You can get a full-body workout anytime you want without a single piece of equipment. Using the resistance of your own bodyweight, you can strengthen every major muscle group through its natural range of motion. There are hundreds of movements to try, each with several variations, but here is a short list of basic patterns and example exercises to get you started. See what other variations you can think of.

[Movement] – [beginner exercise], [intermediate exercise], [advanced exercise]

Squat – bodyweight squat, jump squat, pistol/> Bend – bodyweight good-morning, one-leg deadlift, king deadlift/> Push – kneeling push-up, decline push-up, one-arm push-up/> Pull – doorframe row, inverted row, sternum pull-up/> Lunge – stationary lunge, walking lunge, split squat/> Twist – twisting crunch, windshield wipers, hanging windshield wipers/> Gait – walk, run, sprint

If you have fifteen minutes and some floor space, you have all you need. Add a pull-up bar and exercise ball for even more bodyweight options.

Weight Machines

Pros: Simple, Controlled Movements/> Cons: Simple, Controlled Movements

That’s not a misprint. The single exercise machines that live in the gym offer simplicity and safety and not much else. They can be a good option for beginners, older trainees, and people returning from injury. They also work as great “finishers” for those interested in building muscle. However, the fixed path of movement makes strength gains somewhat less transferable to the real world.

Smith machines are more versatile than single exercise machines, but they also have a fixed bar path. Cable pulley machines, on the other хэнд, allow a variety of exercises and angles – you could almost classify them below with free weights. All these machines are expensive, so you generally find them in gyms rather than basements.

Free Weights

Pros: Versatile, Natural Movements, Easy to increase resistance/> Cons: Require strict form, Slightly higher risk of injury compared to machines, Some exercises require a spotter

Free weights are fantastic. With a pair of adjustable dumbbells or a barbell and some plates, you can do hundreds of movements that will build strength in all planes of motion. Unlike most machines, which have a fixed path of movement, free weights require the lifter to control the path of the weight.

This means two things: 1) your body will recruit more muscles to stabilize the weight, and 2) proper form is very important to reduce the risk of injury. People occasionally get injured lifting weights – still far less than most sports – and it’s usually because they let their form suffer. So keep your ego in check, and don’t add more weight to the bar unless you can do so with strict form. Remember that cheating isn’t progress. Progress is progress.

What about dumbbells versus barbells? Both have benefits. With dumbbell upper body exercises, you move each arm independently, so they demand more coordination and stabilization and allow a greater range of motion. With barbell upper body exercises, you move both arms together, making the movement more stable and reducing the range of motion. This means you can really load up the weights to exert maximal force.

When it comes to lower body exercises, grip strength often limits the amount of weight you can use for dumbbell exercises. With barbells, though, you can use a mixed grip (one хэнд prone, one хэнд supine) or rest the bar across your shoulders, allowing you to lift more weight. For both upper and lower body exercises, barbells generally offer a stronger stimulus, and thus require more effort and longer recovery times.

Clearly, dumbbells and barbells have unique advantages, so mix it up to get the benefits of both.

Exercise Bands

Pros: Versatile, Portable, Safe, Cheap/> Cons: Resistance varies throughout the movement

Exercise bands are a great option for travelers or someone on a budget. Especially when combined with bodyweight exercises, bands can help you develop strength in all major muscle groups and through all planes of motion.

Exercise bands differ from other methods of strength training because they depend on elasticity to produce resistance, instead of gravity like bodyweight exercise, free weights, and most machines. In practice, this means that band exercises are usually most difficult at the point of peak contraction, rather than in a stretched or partially contracted position. This isn’t necessarily a bad thing, since new stimuli spark new adaptations, but it does mean that it is more difficult to strengthen muscles in their weaker ranges of motion.

There are two primary ways you can overcome this particular difficulty. The first is to ensure strong tension on the band when your muscles are in the stretched position. In some cases you may only be capable of partial movements. That’s fine. Just be sure to do some full-range movements as well. The second method is to add a gravity component – that is, use bands and bodyweight, or bands and free weights, so that when the band is looser, your muscles are working harder against gravity.

Decisions, Decisions

Now that you know the pros and cons, machines, free weights and bands, you can experiment and choose what’s right for you. Each has its place, broadly speaking, so if you’ve been stuck on machines for years, or if you’ve never touched a resistance band, try a few new moves and see what happens. Your body might thank you.
