I exercise on a regular basis and do a lot of walking but I don’t seem to be getting fitter. I am also tired a lot of the time. Since my body is not responding to my current regime, I wondered what else you could suggest?

If we stick to the same exercise routine week after week, the body gets used to doing those activities and we are less likely to see improvements to our fitness. This may be what's hindering your fitness gains.

For overall health, it is also a good idea to practise a variety of activities. This would ideally be some strength exercises alongside activities that get the heart beating a little bit faster. To achieve this, you could simply up the speed of your walks or, if possible, try something a little bit different. Perhaps a cycle or online exercise class - whatever suits your likes and abilities.

Naturally, it is harder to lose weight as we get older so I wouldn't get too caught up in this. Just focus on eating a healthy varied diet, and maintain regular exercise, as you are already doing.

Low energy levels can be down to various factors but in general I recommend trying the following:

- Up your water intake

- Increase your nutrient intake through fresh foods, particularly magnesium

- Try Balance Mineral Drink (it contains magnesium, zinc, calcium, potassium and vitamin D)

I hope this helps but if you have any other questions, do get in touch.
