Stamina levels dictate your ability to work out at a certain intensity for a duration of time. Whilst endurance levels are mostly a matter of genetics there are two main factors that allow you to improve your stamina; your VO2 max (rate at which a body can consume oxygen during exercise) and lactate threshold (the level of exertion at which lactate accumulates in the muscles). With a targeted training plan you can develop both of these variables.
