What is gymnastics? Types and apparatus
Gymnastics is a sport where you move your body with strength, balance, flexibility and control. Judges give marks for how hard the skill is and how cleanly it is done.
Main types
- Artistic: skills on apparatus. Women: vault, uneven bars, beam, floor. Men: floor, pommel horse, rings, vault, parallel bars, high bar.
- Rhythmic: dance-like moves with a ball, hoop, ribbon, rope or clubs, to music.
- Trampoline and tumbling: high jumps with twists and somersaults.
- Acrobatic: pairs or groups making balances and throws together (pyramids).
In school you mostly do floor work, small apparatus (bench, box, low beam, mini-trampoline) and partner balances.
Basic skills: rolls, balances, jumps and vaults
Rolls
Forward roll: squat, hands on the mat, tuck the chin to the chest, push with the legs, roll on the back of the shoulders (never the head), stand up without using hands. Backward roll: hands by the ears, palms up, roll back and push the floor away.
Balances
Static positions held for about 3 seconds: scale (arabesque), V-sit, headstand, handstand, and partner balances. A balance is easier when the base is wide and the body is tight.
Jumps and turns
Straight jump, tuck jump, star jump, half turn. Land softly: bend the knees, feet hip-width apart, arms forward.
Vaults
A vault has five phases: run-up → take-off from the springboard → push-off with the hands → flight → landing. School vaults are the squat vault (knees pulled between the arms), the straddle vault (legs wide apart over the box) and, for advanced pupils, the handspring (body goes over the hands and turns once in the air).
Routines
A routine joins skills smoothly: start pose, 4–6 linked elements, end pose. It is judged on difficulty, execution (clean shape, pointed toes, straight legs) and flow.
The science: balance and spinning
Centre of gravity and base of support
The centre of gravity is the point where all your weight seems to act. In a standing person it is just below the belly button. The base of support is the area under and between the parts touching the floor. You stay balanced while a vertical line from your centre of gravity falls inside your base. A wide base and a low centre of gravity make you more stable; a beam or a handstand has a tiny base, so it needs constant small corrections.
Why a tuck spins faster
Once a gymnast leaves the floor, the amount of spin they have (angular momentum) stays the same. Pulling the body close makes it easier to turn, so it turns faster. Opening out slows the spin, which is why gymnasts open up before landing. A tight tuck can spin about 3 to 4 times faster than a straight body.
Pushing and landing
The springboard and the floor push back as hard as you push on them, so a strong push gives a higher jump. On landing, bending the knees spreads the stop over a longer time, so the force on your joints is smaller.
Safety, warm-up and fitness for gymnastics
- Warm-up 10 minutes: light jogging, joint circles, dynamic stretches. Cold muscles tear more easily.
- Mats under every skill; check apparatus is stable before use.
- Spotting: a trained helper supports you at the hips or shoulders while you learn a new skill.
- Progression: learn easy versions first (roll down a slope before a flat roll, handstand against a wall before a free one).
- No jewellery, hair tied, fitted clothes, bare feet or gym shoes.
- Stop if something hurts. Never practise a new skill alone.
Gymnastics builds strength (core, arms), flexibility (splits, bridge), balance, coordination and body awareness. India's Dipa Karmakar finished fourth on vault at the 2016 Olympics, showing how far careful training can take you.

Worked examples
1. Why do gymnasts on a beam stretch their arms out sideways?
Arms out help them shift weight quickly to keep the centre of gravity above the narrow beam. Small arm movements correct small leans before the line from the centre of gravity leaves the base.
2. A gymnast spins 1 turn per second in a straight shape. In a tight tuck the body is about 3.5 times easier to turn. Roughly how fast does the tuck spin?
The spin amount stays the same, so the speed goes up by the same factor: about 3.5 turns per second.
3. List the safe teaching order for a handstand.
1) Strengthen arms and core (plank). 2) Kick up against a wall. 3) Handstand with a spotter holding the legs. 4) Free handstand on a mat, rolling out forward if you overbalance.
4. Plan a 6-element floor routine for a beginner.
Start pose → forward roll → straight jump with half turn → V-sit balance (3 s) → backward roll → star jump → end pose with arms up. Link each move without stopping.
Common mistakes
- Rolling on the top of the head in a forward roll; the chin must be tucked so you roll on the shoulders.
- Landing with straight, locked knees; always bend the knees to soften the landing.
- Trying a new skill without a mat, a warm-up or a spotter.
- Opening the body too early or too late in a jump; open just before landing to slow the spin.
