Since I work from home very long hours (9-12h) every day and do not have to conmute, I force myself to be constantly active.
I do swimming, bike riding and short workouts (30 min) at a gym 2-3 days a week. Normally I finish my workouts doing abs, and since I learned some moves with the exercise ball I only train them directly with the ball now.
Recently I am wondering if getting a ball for home will make a big difference.
One one side I want to replace my chair for a couple of hours, mostly to add some variety to my posture. On the other, I could forget about direct abs training at my gym and add some extra exercise. On the recovery days I could just do just some short-intense abs training separate from other exercises.
Is it worth the idea? Does is sound like a good thing to do? Could I overdo abs or hinder recovery by training that way? I always disregarded the ideas of home training and ball-chair but thinking about the sitting variety and moving off direct abs training from my gym seems quite sound.
