Very good 'new' idea and safely performed along with good solid instruction.

I rate this video with 1 star because it is not a squat and not a kettlebell specific exercise. If we use a kettlebell as just a piece of iron, no different than any other weight, there is no reason to create a separate exercise video. It would be better to show one exercise and let the users know many types of resistance equipment can be used. Holding a medicine ball, dumbbell, or kettlebell in this video does not change the exercise in any more than a cosmetic way. Additionally, the exercise shown here is not a squat, but a lunge with the back leg off the ground. The upper body posture in a squat (single leg or other) is completely different as is the relationship of the load to the foot-ankle-knee-hip complex. To further demonstrate the lunge they actually do a lateral lunge towards the end. She stops him when he brings his leg forward which could have led to a squat if he changed his posture. A kettlebell exercise is one where a kettlebell is needed such that the use of a kettlebell provides a different result, such as a swing or a snatch. A kettlebell swing and a dumbbell swing are very different. Finally, the word squat should be reserved to exercise that include squatting.

The person is getting stabilization connection to help a proper squat. this also shows that a kettle can be used for other exercises also if thats the only equipment available. i would prefer if the demonstrator go into a full squat position vs a partial especially when the non weight bearing leg is in front. a side view will help also.
