Exercise and Cardiovascular Health Study Findings

In a recent study, researchers investigated the relationship between exercise frequency and cardiovascular health in adults aged 30 to 50. Over a span of six months, they monitored the participants' exercise habits through surveys and assessed their cardiovascular health by measuring blood pressure, cholesterol levels, and heart rate recovery post-exercise. The results were categorized as follows: Group 1 exercised less than once a week, Group 2 exercised 1-3 times a week, and Group 3 exercised more than 3 times a week. The findings indicated that Group 3 had significantly lower blood pressure and cholesterol levels compared to the other two groups.

Based on these results, which of the following conclusions can be drawn regarding exercise frequency and cardiovascular health?
