The safe thing to do would be to assume that it will stay in your body as long as marijuana (THC) normally stays in the human body: around 2 to 6 weeks, or about a month on average.
It also depends on what kind of test. A hair folicle test can test positive for years.
b. during an intense exercise routine
EPOC ( excess post-exercise oxygen consumption) is used for the recovery of both anaerobic & aerobic metabolism. The more anaerobic or intense the exercise is, the greater the oxygen deficit is and therefore the more EPOC is required to return the body to a pre-exercise state.
DOES EXERCISE INCREASE METABOLISMYes, exercise does increase metabolism. Your metabolic rate is the speed at which the chemical processes of your body produce energy and growth. If you remain physically inactive, nothing much will change; your body will just stay as it is. Exercise forces your body to work harder to adapt to the exercise, which is why it increases your metabolic rate.Cardio exercise forces (primarily) your body's cardiovascular system to work harder. Your heart and respiration rates will increase as you exercise, because your muscles are working harder so they need more fuel, including oxygen, and generate more waste products that must be transported away.Strength training (weight training) stimulates overcompensation for the stress you have deliberately placed on your muscles, connective tissues, and skeleton. Your muscles will increase in size, your connective tissues will strengthen, and your bones will thicken.Therefore, both cardio and strength training make your body work harder. In working harder, your body uses more energy. That increased energy is why your metabolism increases.For information about how to use exercise to increase your metabolism, use the page links listed below:Two mild cardio plans to increase you metabolism via exercise (one easier plan, one harder plan)Does exercise increase metabolism via an intense cardio exercise planWhat can increase your metabolism in other ways

You can alway add more activity, but that could be tough. Instead, work on new forms of activity. For example, interval training (2 or 3 minutes of intense exercsie, a few minutes or regular or light exercise, 2 minutes of intense exercise, 2 minutes of regular exercise, and so on) has been shown and studied and proven to increase intensity and calorie-burning processes during exercise. Drinking green tea and ice water throuhout the day also helps to boost your resting metabolism.
anaerobic exercise
A goal of losing ten pounds of body weight quickly can be achieved through a combination of diet and exercise. Eating five or six small healthy meals a day at three-hour intervals will provide your body a constant supply of energy and increase metabolism. Walking is a great exercise for elevating a body's metabolism. The website Intense-Workout.com will provide further information. http://www.intense-workout.com/small_meals.html
