It appears like you have weight management
issues. The current recommendations are moderate exercise (For example brisk walking) for 40 minutes. Firstly, eat a healthy diet consisting mainly of fresh fruits and vegetables, and avoid junk food like fried food and colas. Avoid strenuous exercise for now. Chest pain
can occur after rigorous exercise. You need to check your Blood pressure in a state of rest and avoid taking stimulants like coffee or smoking
within an hour of measuring your Blood pressure. Nothing to worry as of now. Follow this regimen and let me know. Last but not least Do not give up :) Keep trying to stay fit.
