I train to lower my body age because at 72 I don't have much more time left to age!  At the gym, I observe many over 50s who should be doing the same, but instead, they are doing things that will make them older.

One reason is that they don't know what else to do. Another is that they believe the myths perpetuated by the bro culture - and the young trainers.

I've been successful in lowering my body age substantially.

Like breaking up, warming up seems hard to do. At least that's my observation based on 20 years of going to the gym.

People seem to hate warming up as much as they hate stretching after a workout.

​They just don't, or won't, do it.

​I've been training now for 20+ years, since I was diagnosed with Type 2 diabetes at 50.

I take it seriously.

Diabetes doesn't just kill you; it does it cruelly - slowly destroying your circulation. Amputations, kidney failure, blindness and dementia result from your capillaries slowly clagging up with excess sugar.

That's why I take exercise seriously as a means of managing my diabetes.

If you're wanting to share some of the results of your gym time with your kids, and do it outside, I have some simple but challenging exercises for you.

My ten-year-old daughter announced that she was going to enter the school cross-country, and asked me to train her.

I was thrilled to have the opportunity to do something outside with her and something physically challenging.

Here's the little program I made for our training. You'll find it fun to do outside with your kids, or just to do something different outside, which will challenge you. These exercises are simple, require no equipment, but give you a whole-body workout, and a good burst of cardio. 

​Hate stretching after a workout, here's a smoother alternative.

I get it, you're tired from the workout, and you don't feel like spending the extra time, and anyway, stretching isn't all that comfortable.

I'm a bit the opposite, as in before running I think "oh I guess I better spend the time warming up or I will regret it" - and I do the thing. After running, I'm OK with stretching as I appreciate the benefits it brings.

No doubt stretching after a workout is a good thing. But let's face it, people don't do it.

I have some good news for you. I can't give you back the time you will need to spend, but doing this will ease your muscle aches and its not discomforting - as stretching can be.

How bored are you with your "leg-day, chest-day, arm day" gym routine? 

If you are looking for something that will get you better results and be more satisfying, then I have good news for you.

Stop now, and you'll be better off.

Training splits, the "leg-day/chest-day/arm-day" guff are just figments of the bro-culture. If you're under 40 no harm done - you'll look good in a t-shirt following any strength-training regime.

If you are over 50, then it's time to stop and think seriously about your training objectives.

If you're a regular reader of mine you may have picked up on my admonitions to not use any gym machines that you sit on e.g. in my Five Secrets for Fitness After 50.

Very often I accompany my warning with the explanation that gym machines are designed to accentuate muscles and make you look great in a t-shirt, but you'll struggle to do up your shoelaces.

There's a reason that gym machines are not designed to help you be able to do up your shoelaces. And there is a much more important reason why that should concern you greatly. It might knock 5 years off your life. When I explain why I hope that you'll kick the habit of gym machines, and potentially live longer better.

You're consistent with your training, but losing your motivation because you've hit a plateau.

Sound familiar? If you are consistent it should, because it happens to us all. I've noticed over the last 20 years of training that as we get older the plateaus get longer. I've had a few people lately express frustration with their plateaus, but don’t give up - all will be well. It's by perseverance that your fitness will get to the next level of reward for you.

The new exercise and physical activity guidelines issued by the US federal government’s Office of Disease Prevention and Health Promotion are better tailored for age and ability. Importantly, they also now take into consideration the intensity of activity, and not just a blanket generalisation of "moderate activity". This is the biggest difference which will most change the potential impact of the new guidelines as compared to the old.

This move to recognise intensity is a very useful change. Previously the recommendations focused people on spending a certain amount of time exercising, including the caveat that spending less than 10 minutes at any one time was not worthwhile. The new guidelines base your dose of physical activity on relative intensity: how much effort a given exercise takes compared with your capacity for exercise. ​They also recognise that short bouts of exercise can be useful - "what really is important is the total amount of physical activity you accumulate during the day and the week".

It's that time of year again where new gym memberships soar, ambitions are high, and lofty fitness goals are set. As we all know, the New Year's fitness see-saw usually ends up with an unhappy ending, unfortunately. Here are my five suggestions to help you create the most sustainable start for your New Year's fitness program.

Trim your ambition and start with much less than you think you can accomplish.

For a start don’t plan an hours session at the gym every day of the week, and don't plan 5:30am classes if you normally don’t even get up until 6:30am. It's better to add more later than to start and then try to subtract. Most people don't end up subtracting successfully - they stop altogether. You only need start with 3 gym sessions a week, make one focused on cardio e.g. a spin class, one on strength e.g. a Bodypump class, and one on functional exercise e.g. Pilates or Body Balance.

​Classes are the easiest way to get a pattern established and you don’t have to think about what to do next.
