I decided to add jump squats to my routine. I have seen them done 2 ways, one the person continuously jumps. The second the person squats, jumps and lands in a squat, then stands back up to reset. Then the next rep is done. Which way would be better, with the goal using it as an accessory to help add weight to the regular squat? I am leaning toward the second, but I'm not really sure as I have not done anything like this since high school.
