Human: I'm going to the gym for the first time. What exercises should I do? Assistant: 
The best exercise you can do at the gym is strength training, which involves using weights or resistance bands to build muscle and increase your strength. You can also try cardio machines such as treadmills, stationary bikes, and rowing machines to get a cardiovascular workout. If you're new to working out, start with light weights and gradually increase the weight as you become more comfortable. For aerobic exercises, try walking on the treadmill at a moderate pace, or use the bike or rowing machine at an easy intensity level.
