If it is a true and false question your answer is: False :)
Only if done on an isokinetics machine otherwise it would be isotonic
A bicep curl is an isotonic exercise.
A bicep curl would be considered a dynamic exercise.
Isotonic exercise (or muscle contraction) is when the muscle contracts and shortens giving movement (ie a bicep curl, lifting and lowering weight) Nearly all the training you do is Isotonic the opposite is Isometric, where the muscle contracts but des not shorten, giving no movement. Eg, Weightlifting, Lifting the weight up and down is isotonic Holding the weight still above the head is isometric
Chin ups work biceps and back; a simple alternative would be a bicep curl for bicep and a deadlift for back strength.
bench pressing.
During a cross body bicep curl exercise, the biceps brachii muscle is primarily worked.
An example of a concentric exercise is a bicep curl, where you lift a weight towards your shoulder. This exercise benefits the muscles by primarily targeting the bicep muscle, helping to strengthen and tone it.
An effective alternative exercise for bicep chin curls is the hammer curl. This exercise targets the biceps and forearms, similar to chin curls, but with a different grip and movement pattern.
Curl (bicep exercise).
An isometric contraction is when your muscles contract but there is no movement. To do one you just need to apply a force to an immovable object. In the strength training sense it is done typically using a power rack or weight lifting cage. The isometric contraction is done typically at the most difficult point of a isotonic lift and is held for 8-12 seconds at maximum exertion. The support pins of the power rack are set at the desired height and a steel bar is then pushed against them to perform the isometric contraction.
The average weight individuals typically lift during a bicep curl exercise is around 10 to 15 kilograms.
Isometric exercises are exercises that are done statically, meaning there is no range of motion while training. The muscles are engaged against a resistance, but do not move. Examples of isometric exercises: The plank for abs, wall sits (sitting against a wall and holding the position), calf raises in which you remain static at the top of the lift. Isotonic exercises cause muscles to contract or extend while engaging resistance. This includes bicep curls, push ups, squats, and most other exercises.
