As a personal trainer I’m always being asked by clients about the best way to tone their shoulders, arms, back and chest so that they can get shaped muscle definition, tighten sagging flesh around the upper arms and have beautiful shoulders to show off in strappy tops.

Up till now I have always talked about dumbbell and resistance band exercises, shown them how to use their body weight to work out or instructed them in the use of resistance machines at the gym. But now I’ve found something new that will tone the entire upper body and the legs as well, is completely portable and lightweight and costs far less than a gym membership. It’s called the Flex Shaper, and I like it, so I’m doing some Flex Shaper reviews. It’s portable, clever, gives great results and is easy to use as well as being good value for money. That ticks all my boxes!

Having one piece of home exercise equipment like the Flex Shaper works out as a bargain as you can tone several major muscle groups with it. Flex it above your head for shapely shoulders; pull it towards you to get a gorgeous back; hold it under your arm to tone those biceps and push it down to trim those wobbly triceps. Even more, the Flex Shaper can also trim your lower body; squeeze the Flex Shaper between your knees to work your inner thighs, and produce sleek, shapely legs.

The unique selling point of this new beastie is the coiled spring bit in the centre which provides resistance in both directions. When you squeeze the handles towards each other (the concentric phase of the exercise) this requires your muscles to tense and shorten, thus making those muscles work and toning them. But with the Flex Shaper your muscles also have to control the return phase of the exercise, unlike conventional exercise tools. This is the eccentric part of the exercise – your muscles are lengthening, but are still having to work.

At this point, if you were exercising with dumbbells or a resistance band you would have to keep repeating the exercise to get the best effect, but the Flex Shaper has made your muscles work twice as hard with just one repetition – so you are doubling your results. This means shorter workouts, which pleases me and my clients no end! And doing this type of workout gives good results in less time, producing long, lean, well-shaped muscles with no bulking-up, and burning plenty of calories at the same time.

It’s quite hard to tone the muscles of the upper back, the top of the shoulders and the front of the upper arm without equipment, so if I had to pick one piece I would probably go with this new Flex Shaper – small enough to be hidden away anywhere in your house, light enough to carry around in your case whenever you go anywhere and versatile enough to tone your entire upper body and your thighs as well. And did I mention that it costs less than a month’s gym membership? Sounds good to me!
