The secret to strength training is no secret. We all know what needs to be done to lose weight and or build muscle. Eat less and exercise is basically for weight loss, and eat ,exercise and rest build muscle. All new programs are just different packaging of same old concepts. All new exercise machines are just modern ways to provide resistance, which is all we ever needed to build muscle. We are so caught up in the newest and easiest way to getting and in shape that we have overlooked what has always worked for hundreds and even thousands of years
As time went on, our concept of power and strength changed. Originally strength started as function but later became sensory. We saw pumped up bodies, are entertained by over developed athletes. But for the common man strength and muscle never changed.
