Working on your fitness matters at every age – and this is particularly true in your 70s when muscle mass starts to decline more quickly. Experts say we lose 3-5% of our muscle mass per decade – which means regular resistance training is vital to stay strong and healthy. So if you’re not already going to the gym, it might be time to get inspired by actor Jane Seymour, who has shown that age really is no barrier to staying strong and supple.

Posting on Instagram, Jane showcased her morning workout which includes Pilates and a unique training method known as the Gyrotonic Method, blending principles from yoga, dance and martial arts to enhance strength and mobility. ‘Starting the day with @gyrotonic and Pilates with weights workout always leaves me feeling strong, centred, and ready for whatever comes next,’ says Jane. There’s something so powerful about taking that time for yourself.’

Jane isn’t the only celebrity who raves about the Gyrotonic Method; the workout – which uses a specialised pulley-tower system – has an impressive list of celebrity fans. It was created by former ballet dancer Juliu Horvath who used the method to rebuild after injury – and today, it’s also used by sports stars for rehabilitation.

As a former professional dancer, Jane knows the value of low-impact workouts to protect her joints, telling Hello! magazine: ‘At this age, I’m looking around me at all the people I know who run, and they’ve had knee replacements, hip replacements or shoulder replacements.’

And it’s not just exercise that keeps Jane strong. In the past, she has credited lifestyle choices for her glowing good health. She tends to eat her largest meal of the day at lunchtime – and has said she tries to fast for 16 hours every day.

Exercise-wise, she works out daily. ‘My body remembers its muscle tone,’ she said. ‘It comes back pretty quickly.’
