How often should you exercise if you have type-2 diabetes? The general recommendation is to lift weights two to three days per week and perform some kind of cardiovascular exercise (e.g., walking, swimming, biking, rowing) four to seven days per week. The weight training should not be too intense (i.e., less than 75% of your 1-rep max which amounts to about 12 to 20 reps before sufficient fatigue) and cardio training should fall within 40 to 70% of your heart rate reserve. It is essential to be aware if you feel dizzy or light-headed. These are symptoms of a low blood sugar level and needs to be addressed as soon as possible. Have a snack and/or glucose tablets available just in case.
