Being strong is the new thin. I love this notion, but can’t claim any credit for it. I got it from Kathy Smith, a fitness guru who is dedicated to ensuring we are “Ageless” by staying strong. I stumbled across Kathy Smith after reading that Michelle Pfeiffer attributes exercise to keeping her looking young. Unfortunately, I didn’t take to her fitness trainer but my online search ultimately led to me coming across Kathy Smith and I absolutely love her energy, philosophy and her Ageless With Kathy Smith Staying Strong DVD.

If strength training isn’t really your thing, think again and get yourself a set of weights or even just grab a couple of bottles of water. By the age of 60, the average person will have lost a third of their muscle mass. But you can reverse it with resistance training - there’s no age limit on our ability to add muscle. Strength training also increases bone mass. And it sculpts your body –  that will make you look younger than any eye cream.

There are four 15-minute strength training workouts on the Ageless With Kathy Smith Staying Strong DVD. They are devised for older people who want to get strong and fit, but don’t be fooled – these are challenging workouts for any age and most levels. I exercise a lot and am fairly fit, but I found Ms Smith, who is probably about 10 years older than me (and way more ripped!), tough to keep up with.

It is a pleasure trying though. She has a boundless energy and such a sunny, positive attitude that the workouts just fly by. Her upbeat “just one more set” coaxed me to keep going and what’s more I could tell I was getting results. Each workout targets arms, legs, glutes and core and combines cardio, resistance, balance and stretching. The goal is strong but long and lean muscles (not bulky ones).

Staying Strong is a great workout for increasing stamina and attaining a more youthful body. Although it is challenging, you shouldn’t be put off as the charming Ms Smith will have you surprising yourself at what you can do. I now regularly alternate my Bar Method workouts with Staying Strong and I’m looking forward to getting to know some of Kathy Smith's other programs.
