Advantages	Disadvantages
Isometric	Does not aggravate sensitive joint surfaces. Easy to perform and remember. Reproducible. Easy to measure. Convenient. Cost effective.	Not functional. Any improvements are speed and angle specific. Many contraindications. Not efficient in terms of strength. No endurance enhancements.
Isotonic	Functional. Easy to monitor. Minimal equipment needed. Convenient. Best strength and endurance enhancements.	Maximal loading only at specific angles. Momentum key factor. Synergists either limit progress or are under trained. Unsafe for joints. Highest likelihood of injuries. Gives delayed onset muscle soreness. Many contraindications. Difficult to monitor accurately.
Isokinetic	Maximal loading throughout whole range of motion. Objective, reproducible and easily quantifiable. Muscles easily isolated. Safest form of exercise. Few contraindications.	Time consuming. Requires a lot of training and skill to use. Costly. Not functional.
