Increasing power and strength
As an athlete your physical ability to perform is based upon your level of 'fitness' across a number of physical attributes such as co-ordination, accuracy, power, flexibility. Two attributes; strength and power are vital for many types of sport and competition. Strength is your ability to exert maximal muscular force over a short time or limited number of repetitions. Muscular endurance on the other hand is your ability to exert a less than maximal force over a longer duration or higher number of repetitions.
