The topic at hand is about exercising with an ostomy and understanding what activities are safe or should be approached with caution. If you're looking to get back in shape and are curious about high-intensity workouts like "Insanity," here's some friendly advice and insights from others who have been in your shoes:

1. Start slowly and listen to your body. Many people with ostomies successfully engage in activities like 2-hour daily workouts, sit-ups, boot camps, running, rowing, CrossFit, and Olympic weightlifting. The key is to ease into these activities gradually.

2. Stay hydrated, especially if you have an ileostomy. It's important to drink plenty of water before, during, and after exercising to keep your body well-hydrated.

3. Know your personal limits. Some individuals may develop abdominal or parastomal hernias and need to modify their activities. Consider low-impact or weight-supported exercises, such as pool exercises like leg lifts and crunches in deep water, which can provide a full workout without straining your body.

4. If high-impact cardio feels too intense, try home-based walking programs. One suggestion is Leslie Sansone's DVDs, like "Walk Yourself Thin – Punch Up Your Walk," which offer total-body movement at your own pace. These programs can be done comfortably at home.

5. Running 3 miles several times a week is achievable for many. Just make sure to wear comfortable gear and keep an eye out for any pouch or skin irritation.

6. The general consensus is that there is virtually nothing you "shouldn't" do solely because of an ostomy. Feel free to experiment with different activities, progress cautiously, and always stop if you experience pain or notice any bulging around the stoma.
