Exercise needs vary among people due to a number of factors, including…
Genetic variability
Genes play a big role in determining a person’s response to exercise. Genetic variations influence factors such as muscle fibre composition, metabolism and cardiovascular capacity. Some people may be naturally predisposed to endurance activities, while others may have a genetic make-up that favours strength exercises.
Metabolic Rate
Metabolic rate varies between people due to genetic and physiological factors. Some people have a higher basal metabolic rate, meaning they burn calories faster while at rest. This affects energy expenditure during exercise and influences the type and intensity of exercise needed for weight management and fitness.
Body composition
Variations in body composition affect how a person responds to exercise. Someone with a higher percentage of lean muscle mass may have different strength and endurance capabilities to someone with a higher percentage of body fat.
Age
Exercise requirements change over the course of a person’s life. Children and adolescents may have different needs for growth and development compared to adults or older people focusing on bone density and functional abilities.
Personal goals
Not everyone wants to get faster or be stronger. Most people have their own goals when exercising and the plan they follow needs to cater to those goals. Personal preferences also come into play, as some people prefer exercising in a team or class, while others prefer solo workouts.
In between exercise
Activity levels between workouts will also influence a person’s exercise needs and how much they eat. If you’re in an active job, for example, you might not need as much exercise as someone who is more sedentary. Recovery is also important, as this is where the majority of your gains are made. Everyone has different recovery times, even after doing the same workout.
Psychological Factors
Psychological factors, including motivation, stress levels and mental health also affect exercise preferences and adherence.
Recognising and embracing these differences is vital for tailoring effective and sustainable exercise programmes that meet a person’s needs.
