In other news, Irving, after you comment the other night about a SUP, I did some thinking today (which is unusual for a Wednesday, but I'm at home not at work so its probably okay for me to think a bit more than usual).
A kayak would be a lot of sitting, which isn't good for me (if I do sit, it has to be perfect posture, blah blah blah). Also, kayaks are rather heavy, weighing in at 45-60 lbs or more. After doing some research, iSUPs (inflatables) are quite light at only 20-30 lbs which would be a lot more manageable for me. Not only that, SUPs are basically core strength workouts on steroids. The best types of workouts I can do are those that work my core (and walking, cause motion is lotion). So I've switched over to researching iSUPs now, and am highly considering one of those instead of a kayak. Thanks for the tip!
