Kettlebells: Know The Basics

All about Kettlebell

  • Kettlebells are cast-iron weights that are round in shape and have a handle
  • Their shape allows for more variation in grip and movement when compared to dumbbells and other similar devices
  • Some kettlebells are adjustable, allowing you to save space in your workout room
  • Durable and relatively lightweight, they are easy to handle and can be integrated into your routine

What an Adjustable Kettlebell Can Do for You


Kettlebells are a great way to lose weight, increase muscle tone, and add variety to any exercise routine. Given the range of motion covered by each kettlebell exercise, you also accomplish a lot in a brief period; this allows you to power through workouts quicker than you would be using conventional weights.


The benefits of using kettlebells in your workout routine include:


  • Full-Body Conditioning: Using a kettlebell gives you both cardiovascular and resistance training benefits, improving muscle tone and increasing metabolism at the same time.
  • Variety of Movements: When you use a kettlebell, there are a lot of traditional and non-traditional moves you can do, keeping you engaged mentally and physically. From kettlebell swings and squats, to windmills and traditional lateral pulls, there are endless ways to mix up your kettlebell routine.
  • Engages Your Core: Unlike traditional dumbbells, kettlebells are not centrally balanced, meaning a kettlebell workout will also help you build core strength. Using your core also strengthens back muscles, improving range of motion and flexibility.
  • Affordability and Space Savings: Since these kettlebells are capable to be adjusted they take up less space than a full kettlebell set, and MUCH less space than a conventional dumbbell and barbell set. They’re also much more affordable than the latter.


How to Use Adjustable Kettlebells


Most kettlebells have a similar system to adjust them, and it is both simple and safe. The top of the bell will have either a button or button/slide mechanism that you push or slide to unlock the kettlebell. (Note: each model is slightly different. Make sure to check the user manual coming along.) Once you unlock it, simply add or remove weight from the kettlebell to suit your strength level and intended workout. When the weight is where you want it, simply lock the kettlebell again and you’re ready to go.

Easy Kettlebell Exercises You Should Know

For those who are just getting started with kettlebells, here are some exercises you can do. Of course, before starting any exercise routine, consult your physician.


Kettlebell Swing

This is the most basic, and essential move you need to learn. The key is to use a fluid motion and keep your back straight throughout. You may want to try without the bell at first to get the hang of it. Kettlebell swings are great for your hips, arms, and thighs, so long as you do them right. Start with legs hip wide and lean forward, legs slightly bent, with the kettlebell on the floor between your legs.


Hold the bell by the handle, and in one smooth motion, swing it back between your legs, then bring it up quickly to about shoulder height. Repeat 10-20 times to start.


Lateral Lunge and Biceps Curl

Start by standing with your feet together, the kettlebell in your right hand, palm facing in and down at your side. Step to the side in a lunge with your left leg, as you lean forward and lower the kettlebell to shin height. Then, curl the kettlebell up, wrist straight. Lower the kettlebell back down, and bring your left leg back to the starting position. Do as many as you can in 30 seconds, then switch sides (right leg lunging and left arm curling).



Begin standing with feet hip distance apart and grab the kettlebell with your hands on either side of the handle, weight facing up. Hold the bell chest height. Lift the kettlebell towards the right side of your face and slowly bring it around the back of your head to the left side Repeat for 60 seconds at a time, continuously alternating directions (once around to the left, once around to the right).
