I'm working on helping my dad lose weight. He's old and obese. He's done well by walking and working on his diet over the last few months and has lost about 40 lbs from 320 to 280 but I want to give him a bit more now to help him continue to progress and because summer is here so walking is becoming more and more difficult due to heat.
So far I'm toying with leg flutters, "squats" using a broomstick in front of him and going down to a chair, perhaps buying him a kettlebell to do swings OR a sledgehammer to beat a tire with (sorta the same motion so no need to get both), and perhaps an Elite Fitness Band to do some rowing with.
Anyone have any other exercises that would be very accessible?
