Calisthenics is a form of exercise that is often of a variety of simple, rhythmical, movements, that can be done without using equipment or apparatus. They are designed to increase body strength and flexibility with movements such as bending, jumping, swinging, twisting or kicking, using only your own body weight for resistance and even someone else’s body weight plus yours . They are usually conducted in concert with stretches. Calisthenics when performed vigorously and with variety can benefit both muscular and cardiovascular fitness, in addition to improving psychomotor skills such as balance, agility and coordination.
Many groups around the world such as sports teams and military units often perform leader-directed group calisthenics as a form of synchronized training (often including a customized “call and response” routine) to increase group cohesion and discipline. Calisthenics are also popular in schools across the globe.
Isometric exercise or isometrics are a type of exercise where the joint angle and muscle length do not change during contraction (compared to concentric or eccentric contractions, called dynamic/isotonic movements). Isometrics are done in static positions, rather than being dynamic through a range of motion. A parcourse or fitness trail, is a great place to practice, isometrics and calisthenics. Of course you can workout from home. But the parcourse is an advantage.
