Strength training or resistance training is the use of resistance to muscular contraction to build the strength, anaerobic endurance and size of skeletal muscles.
Cardiovascular fitness or aerobic training is exercises such as walking, running, swimming, cycling, cross trainer, spin bike and much more.
A person with great mobility is able to perform functional movement patterns with no restrictions in the range of motion (ROM) of those movements.
General fitness training works towards broad goals of overall health and well-being, rather than narrow goals of sport competition, larger muscles or concerns over appearance.
