How do I get back in shape after years of no exercise?

Getting back in shape after years of no exercise can be a challenge, but it is possible. The first step is to start slowly and build up gradually. Begin with low-impact activities such as walking, swimming, or cycling. As you become more comfortable and your fitness level increases, you can add more challenging exercises such as running, weight training, and HIIT (high-intensity interval training). Additionally, it is important to focus on proper nutrition and hydration to support your fitness goals. Finally, make sure to get plenty of rest and recovery time between workouts to prevent injury and burnout.
