I recent saw an infomercial for The 10 Minute Trainer Workout this product is available for purchase on the net and is high intensity in nature and reportedly will deliver major results in about 10 minutes a day.
I have to admit that I'm skeptical of any exercise program that is high intensity designed to bring about quick results in minimum time because as a ground rule the higher the intensity on an exercise program the higher the exposure to injury. That lead to medical expenses, pain and training down time.
I looked at the exercise models demonstrating the exercises and they appeared to me to have a fairly high level of fitness, higher than the average person whom intent is maybe get a little more healthly or lose a few pounds.
Although some exercise models were actually skinny IMHO and I would love to see them do a few (about 10) Turkish Get Ups with a kettlebell or medicine ball. Getting skinny is not physical fitness, it's getting skinny.
Watching the video I saw a lot of movements such as various kicks, side planks etc. That if a person hasn't exercised for a while probably won't be able to perform. What this can do is discourage a person who may have been sedentary for years from becoming more active by making him or her think that they're physically de-condtioned to the point of hopelessness. I'm sure that this program probably has it's success stories in all honesty.
Bottom line would I personally invest in The 10 Minute Trainer Workout? No! But that's me. I would spend the money on a good pair of walking shoes and get to walking and use a little of the money left over and pick up a small set of dumbbells or maybe try a yoga class but that's me.
