Exercise: Not sure how old you are or if you have risk factors for heart disease. If you have gained weight and have been inactive for several months, it is normal to be breathless when starting a workout. Start slowly, 10 minutes, building up to 30 minutes 5x per week. Stay well hydrated and eat a healthy diet. Anxiety can contribute to this, which is normal. Relax and stick with it.

Deconditioning: Whenever the body does not get the regular exercise it used to get, it does not function as optimally as when there was regular exercise. This may be manifested by lightheadedness, shortness of breath, palpitations, etc. Anxiety can have similar symptoms but not necessarily with exercise.
