One of the most frustrating misconceptions within the fitness industry is the belief that a workout should feel extremely challenging, verging on painful. While (correctly programmed and implemented) high intensity training has its benefits, exercise should never hurt or feel unsafe. So how do you know if you’re pushing too hard, or simply afraid of feeling the burn? Read on to learn some tips from the Nielsen Fitness team of in-home and virtual personal trainers.

MODERATE VS HIGH INTENSITY TRAINING 

First of all, it is not necessary to participate in any form of high intensity exercise if it doesn’t interest you. Though this type of training burns more calories in a shorter amount of time (not to mention the EPOC effect, which means you’re burning calories at an elevated rate for several hours after exercise), this simply means high intensity workouts are more time efficient. 

Unless you’re interested in anaerobic training to improve your power, or a high level of progressive overload to build significant strength, the benefits of any form of (consistent) exercise are the same: both aid in weight management, lower blood pressure and blood sugar levels, improve heart health, and boost oxygen consumption.  Furthermore, any “exercise improves brain health and memory by increasing blood flow to the brain, which helps deliver more oxygen and nutrients needed for brain function. It also boosts the production of a protein called brain-derived neurotrophic factor (BDNF). BDNF supports the growth and survival of brain cells, enhances the connections between them, and helps improve memory and learning” (Very Well Health, 2025).

NO PAIN, MORE GAIN

Secondly, the most important goal of any training program should be longevity. Our in-home personal trainers in Toronto, Collingwood, London, Hamilton, and Ottawa (and virtual personal trainers everywhere) always design programs with this in mind. If you’re not able to maintain your exercise routine, you may be pushing too hard. Your workouts should not leave you feeling too sore to move, grumpy, or fatigued. The idea is to improve your life, so training should feel like an added benefit. 

No pain, no gain? No dice! We want your workouts to feel challenging, yet enjoyable; you should finish with a feeling of confidence. This is what will keep you coming back, and consistent good habits are what define long-term health. “Staying alive is the ultimate goal of life — and exercise can help you do it” (Cleveland Clinic, 2025). 

SAFETY FIRST

Thirdly, the last thing you want to do is injure yourself during training. On top of pulling you further away from your fitness goals, a serious injury can have lifelong consequences. If you ever feel sharp pain, a loss of stability, or even begin to doubt your form and execution, it’s time to speak to a licensed in-home or virtual personal trainer. Our job is to help you understand how your body should function and feel during training, and even daily life. Until you consult a pro, it’s always better to play it safe. The controlled discomfort of an elevated heart-rate or muscle burn shouldn’t feel scary.
