Are slow repetitions better for building strength?

John Spencer Ellis (Author, TV Show Host, Trainer and CEO, National Exercise & Sports Trainers Association) gives expert video advice on: How do I design a strength training program?; How often each should I train each muscle group?; How much weight should I use when I train? and more...

Moving the weight slowly can be advantageous for building strength. However, if everything you do is really, really slow, in general terms, your body will learn to move really, really slowly. In some techniques today, it's exceptionally slow technique. However, what do you do in life that is that slow? That's the question I ask. So, there's no direct application to other things that you may be doing in life. In general terms, doing an exercise, like a bicep curl or a squat very slow will teach you technique; you can focus more on the muscle, it is easier to synchronise the breath with the movement. Those are all good things. I do think it's important to vary the tempo, the speed, and even the sequencing of the movements because your body will get bored and your mind will get bored as well, and it's very likely that you won't achieve the ultimate results that you desire if you stick with just one slow method of lifting weights.
