For those who are not interested in group classes, this is also well earned the right to be a chick. But this does not give you the pass to be potato on the couch. If you sit down, you can also exercise by using a fitness chair ($ 150). Essentially a folding chair with integrated resistance bands that offers more than 50 exercises, all of which can be performed from a seated position. Or, if you don't want to have to assemble a whole thing, grab a few light-resistant strips ($ 10 +) and a set of DVDs with instructions ($ 30). As long as you have a sturdy chair at hand, you can insert reps.
Ergometers, better known as rowing machines, provide unsurpassed cardio workouts for the entire body. The problem is they are quite expensive and if your shape is wrong you can easily exacerbate existing back and joint problems. Stationary bikes, on the other hand, will not work on your upper body, but you can still get a solid cardio workout, such as a recumbent Marcy exercise bike ($ 155). It has a low, stepped design so you don't throw your hips out trying to get on the saddle. The supine position further reduces the tension of the lower back and joints. And at $ 155, you won't have to dip into Grandma's Holiday Fund to pay for it. Hell, you can even build your own DIY Peloton (ask your kids what it is) by combining a recumbent bike with an iPhone or iPad and this free iOS app.
Then again, where is the fun of spending your senior years hanging around the house when there is still so much to go out and see? If you're still mobile enough to not need a walking stick or walker but feel more confident with a stick in your hand, check out Urban Poling's Activator poles ($ 110). Created by an occupational therapist, these walking aids "can be useful for knee / hip surgery, injuries, Parkinson's, stroke, MS, chronic pain, cancer rehabilitation, spinal conditions and adults," according to the product's website.
