Hip hinge

A movement pattern in which the hips travel backward while the spine stays neutral and the knees bend slightly, loading the hamstrings and glutes. It is the foundation of swings, deadlifts, and cleans.

Related: Hip snap, Neutral spine, Swing
Hip snap

The rapid extension of the hips that projects the kettlebell forward during a swing. Power comes from the glutes and hamstrings contracting explosively, not from lifting with the arms or lower back.

Related: Hip hinge, Swing, Hardstyle swing
Hardstyle swing

A powerful, crisp two-handed swing style emphasizing maximum tension, a sharp hip snap, and a deliberate float at the top. The bell typically rises to roughly chest height and the body stays rigid throughout.

Related: Hip snap, Swing, RKC plank
Swing

A ballistic kettlebell exercise in which the bell is repeatedly projected forward by hip extension and returned between the legs. It trains posterior-chain power and conditioning and is the signature kettlebell movement.

Related: Hip hinge, Hip snap, Hardstyle swing
Turkish get-up

A slow, multi-step exercise that takes a lifter from lying supine to standing while holding a kettlebell locked overhead. It develops shoulder stability, trunk control, and full-body coordination through a defined sequence of positions.

Related: Overhead lockout, Windmill, Half-kneeling position
Overhead lockout

The end position of a press or get-up in which the arm is fully extended, the elbow is straight, the bell sits over the shoulder joint, and the ribs stay down. It confirms safe, stacked alignment.

Related: Turkish get-up, Rack position, Shoulder packing
Rack position

A hold in which the kettlebell rests against the forearm and chest with the elbow bent and tucked, the wrist neutral, and the shoulder packed down. It is the start and finish of presses, cleans, and front squats.

Related: Clean, Shoulder packing, Overhead lockout
Clean

A movement that brings the kettlebell from between the legs to the rack position using hip drive and a guiding hand. The bell should tuck softly against the forearm rather than bang down onto it.

Related: Rack position, Hip hinge, Snatch
Snatch

A single-arm ballistic lift that drives the kettlebell from between the legs to a locked-out overhead position in one continuous motion. It demands precise timing to avoid forearm impact and shoulder strain.

Related: Clean, Overhead lockout, Hip snap
Goblet squat

A squat performed while holding one kettlebell at chest height with both hands. The anterior load encourages an upright torso and deeper knee bend, making it a common teaching and regression tool.

Related: Front squat, Hip hinge, Neutral spine
Front squat

A squat with kettlebells held in the rack position on one or both shoulders. The load sits in front of the body, demanding trunk rigidity and keeping the torso more vertical than a back squat.

Related: Rack position, Goblet squat, Bracing
Windmill

An exercise in which the lifter hinges and rotates beneath a locked-out overhead kettlebell, lowering one hand toward the floor while keeping the loaded arm vertical. It trains hip mobility, obliques, and shoulder stability.

Related: Turkish get-up, Overhead lockout, Hip hinge
Anterior pelvic tilt

A posture in which the front of the pelvis rotates downward, increasing lumbar arch and often accompanying a forward-leaning ribcage. Coaches watch for it during overhead work and swings as a sign of lost trunk control.

Related: Bracing, Neutral spine, Rib flare
Bracing

Creating tension in the trunk muscles, including the abdominals and obliques, to stabilize the spine before and during a lift. Effective bracing lets force transfer from hips to bell without spinal movement.

Related: Anterior pelvic tilt, Rib flare, Neutral spine
Rib flare

A position where the lower ribs lift and push forward, often paired with an arched lower back. It signals poor trunk stacking under load and is corrected by exhaling and drawing the ribs down.

Related: Bracing, Anterior pelvic tilt, Overhead lockout
Neutral spine

The natural curvature of the spine maintained without excessive rounding or arching. Keeping it neutral during hinges and swings protects the discs and allows efficient force transfer.

Related: Hip hinge, Bracing, Anterior pelvic tilt
Shoulder packing

Actively drawing the shoulder blade down and back so the humeral head sits centered in the socket. It stabilizes the joint during overhead and racked holds and reduces impingement risk.

Related: Overhead lockout, Rack position, Scapular upward rotation
Scapular upward rotation

The shoulder blade's rotation so the socket faces upward as the arm raises overhead. Adequate rotation is required for a safe overhead lockout and is limited by poor serratus and trapezius function.

Related: Shoulder packing, Overhead lockout, Mobility versus flexibility
Posterior chain

The muscles along the back of the body, including the glutes, hamstrings, and spinal erectors, that extend the hips and trunk. Kettlebell ballistics load this chain heavily and develop its power.

Related: Hip hinge, Hip snap, Swing
Ballistic exercise

A movement in which the body or load is rapidly accelerated and then allowed to float or reverse, such as a swing or snatch. Muscles work through fast, forceful contractions rather than slow grinding ones.

Related: Swing, Snatch, Grind
Grind

A slow, continuous-tension exercise such as a press or get-up in which the load moves without a float phase. Grinds build strength and control, complementing the power emphasis of ballistics.

Related: Ballistic exercise, Turkish get-up, Overhead lockout
Time under tension

The total duration muscles are loaded during a set. Kettlebell grinds and slow eccentrics increase it, which supports hypertrophy and control, while ballistic work keeps it short and power-focused.

Related: Grind, Volume, Density
Volume

The total amount of work performed, often counted as reps, sets, or tonnage across a session or week. Programming volume too high too soon is a common cause of overuse complaints in kettlebell training.

Related: Density, Progressive overload, Deload
Density

The amount of work completed per unit of time, increased by shortening rest periods or adding reps within a fixed window. It is a key progression lever for kettlebell conditioning work.

Related: Volume, Progressive overload, Work-to-rest ratio
Work-to-rest ratio

The relationship between time spent exercising and time spent recovering within a session. Short rests suit power-endurance swings, while longer rests preserve force output for heavy grinds.

Related: Density, Deload, Periodization
Progressive overload

Systematically increasing training stress over time by adding load, reps, sets, or complexity so the body keeps adapting. In kettlebell work it may mean a heavier bell or tighter rest intervals.

Related: Volume, Density, Deload
Periodization

Planning training in phases with varied emphasis on volume, intensity, and skill across weeks or months. It manages fatigue and peaks performance for a goal date.

Related: Deload, Progressive overload, Work-to-rest ratio
Deload

A planned period of reduced training stress, often shorter sessions or lighter bells, allowing recovery and adaptation. It typically follows heavy blocks or precedes a testing week.

Related: Periodization, Progressive overload, Volume
Regression

A simpler or lower-demand version of an exercise used when a client cannot yet perform the target movement safely. Examples include a deadlift instead of a swing or a half get-up instead of a full one.

Related: Progression, Screening, Goblet squat
Progression

A planned increase in exercise difficulty, load, or complexity once a client demonstrates competence. Progressions should follow consistent technique, not a fixed calendar.

Related: Regression, Progressive overload, Screening
Screening

A pre-participation check of movement quality, health history, and joint limitations to identify clients who need modifications or medical clearance. It informs exercise selection before training begins.

Related: Regression, Scope of practice, Informed consent
Informed consent

A client's voluntary agreement to participate after being told the risks, benefits, and alternatives of training. Coaches document it before starting and refresh it when programming changes significantly.

Related: Scope of practice, Screening, Liability
Scope of practice

The legally defined boundary of what a certified coach may do, such as teaching exercise but not diagnosing injury or prescribing diets. Exceeding it risks harm and legal liability.

Related: Informed consent, Screening, Referral
Referral

Directing a client to a qualified professional, such as a physician or physical therapist, when their needs exceed the coach's training or legal limits. Prompt referral protects the client and the coach.

Related: Scope of practice, Screening, Informed consent
Liability

Legal responsibility for harm caused through negligence, such as unsafe instruction or ignored contraindications. Insurance and careful documentation help manage this risk.

Related: Informed consent, Scope of practice, Referral
External cue

A coaching instruction that directs attention to something outside the body, such as pushing the floor away or snapping the hips to the wall. It often improves performance more than internal, body-focused cues.

Related: Internal cue, Hip snap, Verbal cueing
Internal cue

A coaching instruction that directs attention to a specific body part, such as squeezing the glutes or tucking the ribs. It suits skill acquisition and correcting a precise positional fault.

Related: External cue, Verbal cueing, Rib flare
Verbal cueing

Using short, specific spoken phrases to shape a client's movement during a set. Effective cues are brief, timed to the moment of correction, and limited to one or two points at a time.

Related: External cue, Internal cue, Regression
Kettlebell history

The development of the kettlebell from a Russian farm and market weight, called a girya, into a formal strength sport and widely used fitness tool. Knowing it grounds claims about benefits and tradition.

Related: Girya, Girevoy sport, Ballistic exercise
Girya

The Russian word for kettlebell, historically a cast-iron weight used in markets and farm work. Its use for conditioning and competition grew in Russia before spreading internationally.

Related: Kettlebell history, Girevoy sport, Pood
Girevoy sport

The competitive Russian kettlebell sport featuring timed lifts such as the jerk, snatch, and long cycle, judged on repetitions and technique. It emphasizes efficiency and endurance over maximal force.

Related: Girya, Kettlebell history, Snatch
Pood

A traditional Russian unit of mass used for kettlebells, equal to roughly sixteen kilograms. Competition bells are commonly sized in poods, so coaches convert to metric when programming loads.
