So here is my dilemma;
I am a 21yr old Exercise Science undergrad and I am at my parents house for the summer. My father is seeking a weight loss program but is very limited time wise bc he is a semi truck driver with 10hr night shifts. His diet really is not that bad, I have been able to introduce wholesome real food into his diet. He does drink a boat load of coffee yet and not enough water. I have tried changing this but he says he needs to stay awake. So my question is what exercise should I suggest for him? I would really like to introduce some form of HIIT but it would need to be soft on the joints and simple. My education has done a great job of teaching me how to handle an athlete or a younger person but I need some help with the older, overweight population.
Any comments would be greatly appreciated guys!
