I used to run out of energy during the day and had a hard time doing simple tasks. I had become unhealthy and lost some of my independence—I felt frustrated! Zumba classes became a way for me to take back my health and independence. I have more energy, and I can perform tasks that require squatting or bending over much more easily. I lost 30 pounds, and my blood pressure has dropped to a healthy level. I feel great about my health and what I can do! The instructor Rosa and the gym staff made me feel welcome. Rosa is happy to adjust exercise difficulty to fit whatever you can do, and no one will judge you for it. Try out Zumba—your health is worth it!
