For a long time, dumbbells have been a fixture in gyms owing to their wide variety of uses. The kettlebell — which is an iron-cast piece of equipment which looks like a ball with a handle — dates back centuries. Whether dumbbells or kettlebells are better for resistance training is a challenging question. While proponents of each of these pieces of equipment have strong opinions about this, the truth is that it actually does come down to personal preference.
Why Is The Centre Of Mass Important?
The centre of gravity of the kettlebell and the dumbbell is important to understand as it has the potential to move the stress of the external load being put on the desired muscle and joint with the exercise that you choose to perform.
The reason why centre of mass matters for choosing between kettlebells and dumbbells is based on different exercise’s strength curves. A strength curve involves how an exercise alters in difficulty through different ranges of motion. To take it a step beyond, a strength curve’s difficulty is not constant as the different pieces of exercise equipment will place different demands on the muscles/joints as they move through different ranges of motion.
When To Choose A Kettlebell
When it comes to explosive and physical movements, kettlebells are king. If your fitness goal is powerlifting, plyo improvements or even if you’re competing in a sport which requires explosiveness (such as basketball or CrossFit games), research offers the suggestion that kettlebells lead to greater gains.
Opt for these to use in exercises that recruit several major muscle groups. These exercises also need to involve moving in a big as well as significant way. Some typical kettlebell moves include the following:
- Snatches,
- Cleans,
- Windmills,
- Turkish get-ups, as well as the
- Kettlebell swing.
Kettlebell swings are also great as they can spike your heart rate so providing cardiovascular as well as strength benefits. Unlike a straightforward curl or press, the kettlebell swing is responsible for activating your entire posterior chain of muscles — in other words, your glutes, hamstrings, and erector spinae (back muscles).
When To Opt For Using Dumbbells
Dumbbells are phenomenal for a little bit of everything. You can begin with more basic movements such as a chest press, shoulder press, a row, or squats with dumbbells held at your shoulders. The advantage is that you’re not swinging the weight around (as you do in a snatch or swing). This makes making the moves a bit more straightforward.
There are pros as well as cons to any exercise. When crafting your strength training routine, make sure that you choose exercises and equipment which are convenient, safe for you, and that will best assist you with reaching your goals.
