What does fitness mean?

Fitness is synonymous with health, Our modernised society has overwhelmingly reduced the tasks and activities we need to accomplish to survive, but the general lack of movement has negatively impacted our health and physical condition. Regular physical activity, even in small amounts, can help prevent, treat, and sometimes even alleviate some of the most common chronic conditions we encounter, including high blood pressure, cardiovascular disease, stroke, obesity, type 2 diabetes, osteoporosis, depression, and some cancers (1,2).


So how much activity is required for fitness?

Two of the most widely recognised activity guideline reports for improving physical fitness include Quantity and Quality of Exercise for Developing and Maintaining Cardiorespiratory, Musculoskeletal, and Neuromotor Fitness in Apparently Healthy Adults:  It is recommend that at least 150 minutes of moderate-intensity cardiorespiratory exercise, 75 minutes of vigorous-intensity, or a combination of moderate- and vigorous-intensity exercise per week. The weekly recommendation for resistance training is 2 or more days per week with exercises for all the major muscle groups (minimum of 1 set of 8-12 repetitions for each muscle group). Flexibility and neuromotor exercises (balance, agility, coordination) are also recommended at least twice per week.

The key phrase to note is “at least” with more benefits being realised with more activity. But what if you aren’t quite ready to tackle these recommendations?  Those 150 minutes of moderate-intensity cardiorespiratory activity are to be spread out over the week, ideally 30 minutes a day, 5 times per week. Consider that those 30 minutes can be further broken down into 10-minute bouts of activity. Some individuals may even need to start with as little as two minutes of walking and build their way up to 10 minutes over days, or even weeks. The goal is to keep motivated and to increase your activity and succeed. Even if more activity is better, a little activity beats none at all.

Don’t discount the importance of also increasing unstructured non-exercise activity thermogenesis (NEAT) (4). These are the activities beyond sleeping, eating and “intentional exercise” that include daily motions such as standing, walking, using the stairs, fidgeting, yard work, and multiple other movements we make throughout the day. Unstructured physical activity is the foundation that can help people realise that just being active, rather than sedentary, can impact their overall, long-term health.

Have a goal

Understandably, goals need to be explored to discover just how much activity may be needed and over what associated time frame in order to reach those goals. For someone wanting to adopt a healthier lifestyle, finding enjoyable activities with a realistic schedule are essential. So in other words, don’t aim to run a marathon in 6 weeks as this is not achievable safely and it would put you off for life! start small and build.
