Which factors can affect a person’s exercise program adherence?

The correct choice highlights essential psychological and social factors that significantly influence a person's ability to adhere to an exercise program. Motivation is crucial; it drives individuals to start and continue their exercise routines. When someone is genuinely motivated, they are more likely to overcome obstacles and maintain consistency in their activities.

Support systems, such as family, friends, or workout groups, provide encouragement and accountability, which can enhance commitment to an exercise program. Having a strong support system can make the experience more enjoyable and can also help individuals set and achieve their fitness goals.

Individual preferences play a critical role as well. When an exercise program aligns with someone's interests, skills, and lifestyle, they are more likely to enjoy and stick with it. Choosing activities that the individual finds fun or fulfilling fosters long-term adherence rather than forcing oneself into forms of exercise that may be viewed as tedious or unenjoyable.

In contrast, factors mentioned in the other options, like genetic predisposition or weather conditions, may have some influence but are not as directly impactful on an individual's adherence to an exercise program compared to motivation, support, and personal preferences. Age and dietary restrictions can also affect exercise routines but still do not encompass the broader, more significant social and motivational dynamics that play a critical role in sustaining exercise
