Planche (exercise)

Planche (exercise) is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Planche (exercise) rather than just read about it. In short: A planche (from French planche, meaning "plank") is a skill in gymnastics and calisthenics in which the body is held parallel to the ground, while being supported above the floor by straight arms. It is a move that requires significant strength and balance.

Key takeaways

Planche (exercise) belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Planche (exercise) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Planche (exercise) from memory before moving on to harder problems.

Reference excerpt

A planche (from French planche, meaning "plank") is a skill in gymnastics and calisthenics in which the body is held parallel to the ground, while being supported above the floor by straight arms. It is a move that requires significant strength and balance. There are many variations of a planche, although only two are accredited in artistic gymnastics: the straddle planche, and the full planche. Depending on the event, it can range from an A to a D skill, and must be held for at least two seconds. As an example, on gymnastic rings, the straddle planche is an A value skill, and the full planche is a C value skill. On floor, straddle/full is A/C. The main muscles used in this exercise are the anterior deltoid and the biceps, but the abdominals, chest, shoulders, lower back, and glutes also play important roles. As the planche is a demanding position, athletes train for it with a progression of simpler moves, advancing to the next when they have gained mastery of the intermediate positions. A typical training progression usually consists of the frog stand, tuck planche, advanced tuck planche, straddle planche, and then full planche. The planche requires arms to be locked at all times.

Muscles used The muscles used in planche are:

Biceps Triceps Deltoid Brachialis Biceps femoris Gluteus maximus Latissimus dorsi Pectoralis major Serratus anterior Soleus Supraspinatus Trapezius Quadriceps Wrist flexors Anconeus Rectus Abdominis

Possible injuries Torn ligaments/tendons in the arms (especially the distal biceps tendon) Wrist injury Shoulder injury Elbow injury Inflammation of the tendons of the arms Injury in back/spine

Worked examples

Example 1 — a first encounter with Planche (exercise)

Start with the simplest possible case. Write down what Planche (exercise) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Planche (exercise) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Planche (exercise) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Planche (exercise)

In research: Planche (exercise) appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Planche (exercise) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Planche (exercise) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bodyweight exercises, Static elements (gymnastics), so understanding it makes those chapters shorter.
In everyday life: Look for Planche (exercise) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
