The right exercise for you

Health and Fitness
Exercise is one of the best ways to boost your heart health and overall wellbeing. But what is the right amount and type of exercise? As with many things, the answer is: it depends. People have different health goals, abilities and limitations, so there is no one-size-fits-all answer. At the end of the day, you have to choose the right exercise for you. This can be daunting with all the options out there, so here are some comparisons of different types of exercise to help you make the best choice for you.

High-intensity interval training (HIIT) vs steady state cardio

HIIT refers to short, intense, unsustainable bursts of exercise followed by periods of rest, while steady state cardio refers to a cardio workout using continuous, sustained effort, such as running, cycling or swimming. While some claim HIIT is the new magic exercise program, as with most things, it’s a bit more complicated. Research has found that with regard to calories burned, HIIT isn’t much better than a slightly longer period of steady state cardio. Other research has found that HIIT is safe and effective in people with a range of cardiac and metabolic dysfunctions.1 This research also found that HIIT had better outcomes for aerobic fitness but similar ones for metabolic function when compared to continuous moderate exercise.2

So if you enjoy a challenging, short, intense full body workout, HIIT may be for you. With any exercise, but especially this form, make sure you keep a healthy schedule and listen to your body. Around 3 to 4 sessions per week is usually sufficient strain and can be combined with less intense exercise on off days if you desire. But if you prefer a chilled workout, have more time to spend on your exercise or are injury prone, then steady state cardio may be a better choice with similar outcomes. Either way, make sure you are maintaining form and staying within your personal ability levels.

Cardio/aerobic exercise vs weight/resistance training

Weight training increases weight endurance, muscle tone and strength, and working with free weights can improve stability. Resistance training also helps to maintain bone density, so it is an important part in any exercise program, especially as we age and our bone density begins to decrease. Some research has shown that resistance training may also be more beneficial in increasing the calories burned due to exercise than steady state aerobic exercise.2

Other research has shown similar outcomes in weight management when either resistance training or aerobic training was used in conjunction with a healthy diet. However, aerobic training appeared to have greater benefit on reducing body fat and improving cardiorespiratory fitness, while resistance training seemed to be better at building muscle.3

Aerobic vs resistance vs combined training

So should you focus on aerobic training? Resistance? Both? Research on the effect of aerobic, resistance and combined training on cardiovascular disease risk factors found that in people at risk of cardiovascular disease, a combination of resistance and aerobic training seemed to have better results on the factors measured (which included blood pressure, cardiorespiratory fitness, blood glucose, body composition and strength) than aerobic or resistance training individually.4, 5

Other research suggests that a combination of resistance and aerobic training is one of the best options to assist in managing diabetes.6 Combination exercises appear to help maintain blood glucose control and modulate other cardiovascular risk factors.

The right exercise for you

If you want to find the best exercise for you, trying a range of different exercises and working out what you enjoy most, as well as trying to incorporate a range of activities, seems to work best. You may also want to consider these factors:

  • Do you enjoy the exercise? This is one of the main elements that determines if someone will continue to do exercise, so choose something you enjoy rather than the “right” kind of exercise. Also choose something that incorporates some form of aerobic element as well as weight bearing/resistance.
  • Can your body handle the exercise? For example, High Intensity Interval Training may not be the best for someone just starting to exercise or recovering from a heart issue.
  • Is it easily accessible and does it fit your schedule and time limitations? Avoiding potential road blocks in your exercise program is easier than overcoming them. One reason programs like F45 have become so popular is that less time is required and they are more available.
  • Will being held accountable help? For those who might need some extra support, joining an exercise group or getting a personal trainer could be just the motivation needed to stick to their exercise program.
