"i am a mother of 3 with an office job and do not workout while taking this medicine. the reason i don&#039;t workout  is because it increases your heart rate to the equivalent of what it would be if you were to go for a run. i&#039;m no cardiologist or medical expert but i don&#039;t feel like you should increase the heart rate beyond that point by actually working out. there is a certain heart rate that is unsafe based on age, height, weight.. etc... now that i&#039;ve said that, i started taking this medicine on thursday june 9th 2016. i weighed in this morning june 13th 2016 and i&#039;ve lost 9lbs in 4days! that&#039;s awesome. i&#039;m on a no carb/low carb diet so every so often i take in some carbs it&#039;s almost impossible to avoid them. i also drink nothing but water."
