I think it is important the way you handle your sail. On flat water the thing you need to do is sheet in with your sail, but as you launch you press down with your back leg to get the board up and then pull up your front leg so the nose comes up. Once you are airborne you make sure you put your nose into the wind. Once that happens you pull in your back leg as well. This technique helps you to get off the water. The point is to bring the bottom of the board into the wind while sheeting in the sail and lifting your back leg. It is an explosive manoeuvre so I think jump squats are great for this. I think that is a pretty similar movement. It is a very coordinated move. You need to coordinate the sail pulling and the jump. For a chop hop it’s the same thing only that you have help from the chop for the launch. If you can ‘pop’ a board in flat water then you can chop hop. While you press with your back leg you pull in your front leg and you sheet in, then you pull in your back leg as well.
