Phase 2.
You must get a doctor’s ok before continuing.
Continue the Phase 1 activities, adding resistance training (1 set of 10-15 reps for the major muscle groups on 2-3 days per week) and vigorous aerobic activities such as running, walking, cycling, or swimming (3-4 days per week for a period of from 20-60 minutes).
Start with the distance you can cover without undue fatigue, then gradually increase until you can do one of the following: run 3 miles, walk 6 miles, cycle 12 miles, or swim ¾ mile (usually 20-60 minutes).
The work-out should also include a 10-20 minute initial warm-up and a 5-10 minute cool-down following the aerobic activity.
