Verified step by step guidance

1. Understand the recommended exercise guidelines: Adults should aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities on two or more days per week.
2. Evaluate Austin's current routine: He goes for a 2-hour bike ride twice a week, which totals 240 minutes of aerobic activity. This exceeds the minimum aerobic activity recommendation.
3. Assess the strength training component: Austin does one strength workout per week using heavy weights. This does not meet the guideline of at least two muscle-strengthening activities per week.
4. Identify the gap in his routine: While Austin meets the aerobic activity recommendation, he falls short on the muscle-strengthening activities, as he only performs one session per week instead of the recommended two or more.
5. Recommend adjustments: To meet the guidelines, Austin should add at least one more muscle-strengthening activity per week. This could include exercises using resistance bands, bodyweight exercises, or additional weightlifting sessions.
