How Staying Fit Changes in Your 30s, 40s & 50s


By UK Personal Trainer

Jamie Bantleman

As we get older, our body’s go through different hormonal processes that cause us to make certain changes to the way in which we approach our training.

Changes To The Body

During Aging

Muscle Loss

During the aging process, something that can occur is Sarcopenia.

Clinical relevance for sarcopenia is defined by a loss in lean muscle mass and impairment of functional status.

A therapeutic approach to the loss of skeletal muscle mass and strength in older persons depends on correct classification.

The term sarcopenia is reserved for age-related decline in muscle mass not attributable to the presence of pro-inflammatory cytokines.

For individuals with sarcopenia, the primary intervention should include resistance exercise. An improvement in muscle mass and strength has been demonstrated with resistance exercise, even in the very old (1)

Bone & Mineral Density


The ageing process also decreases bone and mineral density. It has been found that when you uptake a resistance training programme you are more likely to have improved bone and mineral density. It has also been found to improve the situation with those who have already been diagnosed with osteoporosis or osteopenia (2).

Female Specific


Menopause can occur anywhere between ages of 20-50, most commonly from 40 onward. This will mean that the oestrogen levels in females will drop significantly usually symbolising the end of fertility.

Asides from side effects such as hot flushes and emotional imbalances, the stress of the hormonal fluctuation causes an increase in cortisol which may increase body fat.

? Therefore, when working out throughout this period of time, you should aim to maintain a good quality training programme that will involve higher intensity workouts over a short period of time. This will help improve fat loss and manage cortisol levels in the body.


In terms of nutrition, maintaining a diet plan that includes high protein and healthy fats to ensure balanced blood sugar levels.

There is also the damages in which every day life can create, the stresses of work, bills, family and environmental stresses.

healthy fats

When we come out of our younger years, these types of stress levels create new barriers to overcome, it invariably means the levels of cortisol can increase through lack of sleep and other issues in which are created.

? Similarly to aiding of the other ageing effects, resistance training for a short period of time (30-45 mins) regularly will help maintain healthy levels of cortisol.

Male & Female Hormones

Testosterone decrease in men

The male androgen that increases muscle cell development, fat loss and in some cases cognition. As we get older, testosterone is effected and can be decreased especially in those who live a more sedentary lifestyle.

Often people are prescribed Dehydroepiandrosterone at a dosage of 200mg (close to max dosage) and appears to improve testosterone in men over 40 years old.

Further health supplements can be used to help improve testosterone production, such as Vitamin D and Zinc.

Estrogen imbalances in women

The female hormone that regulates the reproductive hormones alongside metabolic processes such as bone growth and cholesterol levels. It can also mediate fat metabolism and cognition.

However an excess in estrogen can lead to an increase in body fat percentage.

Supplements that could benefit women’s health include:
