I am sure most of you have heard of probiotics but are not quite sure of their relevance to human health. Probiotics are live microorganisms such as yeast and bacteria that we orally ingest which are believed to have beneficial effects in our bodies, most specifically our digestive system. We take probiotics in the hopes of re-colonizing our digestive tract with “good’ bacteria and thus overtaking “bad” bacteria which have been linked to a variety of health problems.
I already wrote a blog about the health benefits of exercise but what about strength training? I have heard that lifting weights raises your metabolism higher and longer than aerobic exercise. I was skeptical to say the least. Think of it like this. Most people go to the gym for an hour or so. But they are not lifting weights for an hour. They do a set of lifts which takes 20 seconds or so then they talk to their friends for a minute or two followed by another 20 second set of lifting. If I had to guess I would say we only lift weights for a total of 10-15 minutes per a one hour gym session. How many calories could that possibly burn?
