<human>:  Can you advise me on a good gym routine?
<bot>: I can certainly help! A good gym routine should start with a few minutes of stretching to warm your body up. Then, aim to complete 3-4 sets of 8-12 repetitions of a mixture of exercises targeting all the major muscle groups. Focus on heavier weights with lower reps to build strength. Include both aerobic and anaerobic movements like running, biking, or swimming to build both your cardio endurance and muscle strength. Finish with a few more minutes of stretching to help your muscles relax.
