Of Russian origin (girya) First mention in Russian dictionary in 1704 Used as a standard measure of grain and dry goods Traditional Russian measure – 1 pood = 16 kgs = 35 lbs 1.5 pood = 24 kgs = 53lbs 2 pood = 32 kgs = 70 lbs
Why is a Kettlebell unique? - Shape and size allows for swinging or accelerating that creates “virtual force” - Very powerful training effect from a relatively light weight - Offset center of gravity allows unique loading of shoulder joint on overhead lifts - Research indicates kettlebells can improve many components of fitness: dynamic strength, ranges of endurance, body composition, hypertrophy, flexibility
Drills are divided into 2 categories: Explosion – ballistic drills, typically done for higher reps to improve power output and / or conditioning levels Grinds – slower, “traditional” type strength drills
EXPLOSION DRILLS include: 1. Swing
2. Snatch
3. Clean
GRIND DRILLS include: 1. Squat
2. Press
3. Windmill
4. Turkish Get-Up
Oxygen Cost of Kettlebell Swings (Farrar, et al) 10 college-aged males used the 2 hand swing technique with 16 kg kettlebell (KB) for 12 minutes Averaged swings Average VO2 of ml-kg -1 -min -1 Average HR bpm Average % HR max – % Conclusion – “Continuous KB swings can impart a metabolic response of sufficient intensity to increase VO2 max.”
Kettlebells: Twice the Results in Half the Time? (Porcari, et al) – ACE sponsored research 10 volunteers (both male and female) ages yrs with previous KB training experience Subjects performed a 20 minute interval KB workout.
RESULTS MEANRANGE HR (bpm) % of HR max VO2 max ml-kg -1 -min % of VO2 max Kcals / min
Conclusion: HR and VO2 responses where significantly higher when compared to traditional strength training Interval KB training is highly effective for improving aerobic capacity!
Kettlebell Swing, Snatch, Bottoms-Up Carry: Back and Hip Muscle Activation, Motion and Low Back Loads. (McGill, et al) Goal of this research was to quantify low back loads various swings and carries. 7 college-aged males performed KB swings, snatches and bottoms –ups carries while EMG and kinematic data was collected.
Results: KB swings showed unique lumbar (L4-L5) loading patterns that are opposite in polarity to “traditional” lifting or loading. May explain the anecdotal evidence for KB swings and snatches restoring and enhancing low back function.

Kettlebells: 1. improve strength 2. improve cardiovascular conditioning 3. improve core strength 4. may reduce low back pain 5. ARE FUN!!!!!!!!
