Focusing on those aged 30-50, Moyna explained that this is typically a time where people become less active. As well as exercise, general physical movement decreases due to various lifestyle factors.

However, it is essential that we prioritise this movement, particularly from the age of 30 on.

"For the average Joe or Mary that's out there, between the ages of 20 and 50, yes, you're going to lose some fitness. But anytime during that 30 year period, where there's a sustained period of exercise, you can get back to your optimum fitness level."

Horrifyingly, Professor Moyna says that 'primary ageing' begins to occur at just 30.

"This is where many of the physiological systems - renal, neurological, cardiovascular systems - start to deteriorate and don't work as well as they did prior to that. And that's an inevitable."

Before we despair too much, Moyna says there are plenty of things we can do to future-proof our bodies. For example, muscle mass is something that we will begin to lose as we age, but this can be battled by simple at-home exercises.

If we put the work in now, it will pay off in our later years when our independence and quality of life is on the line.

"What we do throughout our 20s to our 50s is very imporant," he insists. "It's putting an insurance policy in, It's putting money in the bank to ensure that beyond 50 we're going to be functional and have a healthy health span."

While some may be inspired to sign up to the next Hyrox competition or vow to run a marathon, Professor Moyna insists that simple daily movements will suffice.

"I call it 'daily hygiene'," he explains. "Like everything else we do in our life, we should put time aside every day for physical activity."

This activity could be a dance class, a round of golf, or a structured workout in the gym.

Walking, he said, is another important movement to add to the day.

10k steps is a nice goal to work towards but, according to research, you need only aim to add an extra 700 steps to an average day (approx 2k steps) to see an 11% drop in fatal and non-fatal cardiovascular disease. An extra 5k steps would lead to a 51% reduction.

All the benefits, he said, came from going from 2k to about 6-7k - that's the "sweet zone" of base-line aerobic health.

As well as upping your step count, it's incredibly important incorporate two days of resistance training in your week.

Women, in particular, should focus on building their muscle mass from a younger age as they are more prone to reaching a 'frailty threshold' and losing independence as they age.

If you can't face going to the gym, simply incorporate body-weight exercises that focus on your upper body, lower body, core and back (push ups, lunges, squats, planks, etc).

Doing this twice a week - for just 10-15 minutes - will make the world of difference as long as your consistent.
