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 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
bench pressing.
Chin ups work biceps and back; a simple alternative would be a bicep curl for bicep and a deadlift for back strength.
Curl (bicep exercise).
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.
bicep curls
There are numerous exercises a person can do to increase bicep mass. You can do pushups. These require nothing but your own body weight. Bicep curles are another exercise you that be done with anything you can hold in your hand.
There are many various exercise routines that will help strengthen your bicep/triceps area. Some of which are known as: Pushups, Chair Dips, Bicep Curls (done usually with dumbbell weights), and Triceps Extensions.
An exercise like a bicep curl would be an example of a single joint movement. You can also move your thumb by the gliding joint that attaches it to the hand. I'm sure there are many others.
By working out the smaller bicep more than you work out the larger one. For example if you are a righty, usually your right bicep is larger, Therefore if you were doing bicep curls I would do 10 with the right and 15 with the left.
if you're speaking anatomically (as in origin and insertion), the origin of the bicep curl would be its fixed attachment at the supraglenoid tubercle and the coracoid process (two heads), as a bicep curl is an open chain motion (distal end is free moving --> proximal end is the origin). it would be more correct, though, to say refer to it as the origin of the biceps during a bicep curl.
