Welcome to HealthcareMagic Forum. The most common reason for bad smelling urine is dehydration
. If you workout, sweat and do not replace your body with fluids you can get bad smelling concentrated urine. In my opinion you must do a urine test. Increase your fluid intake, take adequate rest and follow a healthy balanced meals. This will solves all your problems. Exercising for about 30 min per day is also recommended. Wish you good health.
