Are Kettlebells Or Dumbbells Superior For Gym Based Strength Gains?

By Russ Howe


It's a war which has raged on for the best part of ten years but, thanks to recent scientific research, today you will get a definite answer to the question: Kettlebells vs dumbbells - which method will give you the best results?

While it's not uncommon to meet individuals who swear blindly that following one protocol is the best way to build muscle and lose body fat, the general consensus is that the optimal results can be achieved through a varied combination of both methods as well as lesser known styles, including resistance bands and suspension trainers.

In an attempt to draw a line in the sand between warring gym enthusiasts who swear by one approach or the other, scientists from California State University, Fullerton recently drew up a study where they could directly compare strength improvements between the two styles.

First of all, we had one study group performing a six week program of kettlebell swings, goblet squats and accelerated swings with a 16 kg weight in a bid to improve squat strength, power clean strength and vertical leap power.

The free weights group performed a six week program of barbell squat, power clean and high pull using around 80% of their one rep max on each exercise.

The results clearly showed that the free weight group enjoyed much greater gains in strength than the kettlebell group. First of all, the barbell/dumbbell group noticed a massive increase in their squat strength of 15%, as well as an increase in power clean strength of 10% and a vertical leap boost of 4%.

The other group, meanwhile, only enjoyed a 5% increase in squat strength, with a 4% boost to their power clean and, somewhat surprisingly, only a 1% increase in their vertical leap strength. The last statistic in particular is quite interesting, given that this piece of kit is often touted as the superior method for increasing explosive movements, such as vertical leaping...

These results clearly document that free weights return superior strength gains overall.

However, this would be ill-advisable. A combination of various different techniques is the key to finding a well balanced, progressive training program which gives you a continuous plethora of new results. By limiting yourself to one training style, you are waving goodbye to various other techniques you could have picked up if you were only a bit more open-minded.

Truth be told, you would do nicely to take small pieces of various techniques and combine them in to your own training routine until you find something which works for you. There are certain things which you can do with a kettlebell that you simply can not accomplish as conveniently with free weights, the swing for example.

So, who wins the battle of kettlebells vs dumbbells? If the latest scientific research is to be used as a barometer to end the argument then you have to jump on the side of free weights.
