If you have followed my blog for any length of time, you are aware that I am not a fan of isolation exercises and I am certainly not in the minority on this topic. Isolation lifts are for bodybuilders or for somebody who is rehabbing a specific body part after an injury. Other then that, you should avoid them and stick to compound type, full body lifts.
Performing isolation type lifts to train your entire body makes training very time consuming and since our bodies don’t work one muscle at a time but rather as one whole unit, isolation lifts are for the most part ineffective.
I have used the everyday example of pushing your car out of the road to demonstrate how the body uses all it’s muscles in conjunction with one another. Lets take that example and examine what happens from the perspective of your nervous system.
When you perform a movement that involves more then one joint, like pushing a car, a kinetic chain is formed. As your legs drive, your quads, hamstrings, glutes and calves all work as a team over the three joints of the ankles, knees and hips. The muscles of the back, abs, arms, shoulders, and pecs are also involved. Pretty much all your muscles will be involved in one way or another.
The efforts of all these muscles must be coordinated. This coordination is developed via your nervous system. This coordination of the efforts of all the muscles involved in pushing your car out of the road is one of the main factors in determining your strength. In other words, strength is measured by how well your muscles work in conjunction with one another, not how strong each individual muscles works independent of the others.
The kinetic chain of coordinated effort developed by your nervous system cannot be established unless you train in a manner that mimics real life. One cannot expect to develop this coordination without training the muscles in such a way that they are forced to work together in groups as apposed to individual muscles.
Full body lifts such as deadlifts or long cycle clean and presses require and thus develop the inter-muscle coordination required to be successful in sports and everyday life situations like pushing a car out of the road or carrying a couch. What you are building training in this manner is functional strength.
Single joint lifts like leg extensions or curls don’t develop this type of strength.
Prof. Fahey of Ohio State University says, “One-joint exercises like leg extensions and leg curls, develop movement patterns that will interfere with patterns you use in sports. Such exercises lead to inappropriate muscle recruitment patters that can impair movement and lead to injury.” Well said professor.

Before entering into a fitness routine, especially one that incorporates kettlebells, be sure to consult with your physician or medical professional to be sure you are healthy enough to begin a strength and conditioning regimen. Be sure to learn the proper way to perform each lift and complete each exercises in strict form employing a spotter when applicable. In other words, if you hurt yourself, it’s your fault.

I have been in the iron game for over 25 years. In that time, I have become a student of how to increase ones strength and fitness. I swear by kettlebell training and can say without a doubt that kettlebells are your one stop source for taking your strength and fitness to extreme levels.
