Re: Why do I get sick after starting exercise program?
My advice would be to not give up. I would get the basics of the workout, like getting a good idea of what the workout is and what the exercises are trying to accomplish. Then take that knowledge and make your own workout. Cut down the duration of each exercise especially, and abbreviate as much as you can. Then gradually work your way up until you can do the workout in full.
I can only comment on examples of workouts I have personally done, but here's a for instance. The workout would be to set a goal 5k pace, for a running race. Then, you would typically run six 1000 meter repeats at that goal pace, with a 3 min jog recovery jog between each one. Since I couldn't do this workout at first, I'd start with 3 and build up over successive weeks. OR, you can do 6 but vary the duration, such as running six 600 meter repeats and gradually lengthen each one until they are all 1000 meters.
You can apply this adaptation approach to just about any workout regimine or program. In fact, this approach is recommended versus just trying the full program right off the bat.
It can be tricky and take some experimentation and even creativity, but think of a way that you can do less now in anticipation that you can one day do the full workout free of problems.
