Is a proper warmup and stretching necessary prior to working out?
YES, The main reason to warm up is to prevent injury. A warmup and stretch help increase the elasticity of your muscles and connective tissues prior to putting them under stress. A proper warmup improves heart function and prepares it for the stress of exercise. There is a tendency for lactic acid to build up in your muscles quicker without a warmup. Lactic acid is what you feel when you are doing an intense exercise and you feel a “BURN”. Warming up and stretching dissipates this lactic acid.
