Most guys can improve their health and aesthetics by building muscle, burning fat or some combination of the two. That gives you three paths to choose between:

• Bulking is the fastest and most reliable way to build muscle. It's when you train for muscle growth, eat a nutritious muscle-building diet, and eat enough food to gain a little bit of weight on the scale each week.
• Cutting is the fastest and most reliable way to burn fat. It's when you train for muscle growth, eat a balanced diet, and dip into a calorie deficit, forcing your body to get energy from your body fat.
• Recomping is when you try to build muscle and burn fat at the same time, usually without focusing on gaining or losing weight. It works best for people who are overweight, out of shape, and not in the habit of lifting weights.

Most guys who want to improve aesthetics can benefit from strengthening their entire bodies while putting extra emphasis on their upper bodies. These workouts are perfect for that. When you finish it, do this program next.

Once you're reasonably muscular and lean, you can focus even more on certain muscles and proportions. For example, if you want to bring up your arms, you can do an arm specialization program.
