Throughout the course of this unit, I made multiple plans and made changes to them repeatedly in order to improve them and customize them to better fit my clients, which were my group members or family members. I changed the plans based on what feedback I was given, which normally told me that I could focus more on working other parts of the body, or to make the entire routine a little less challenging by decreasing the duration of each exercise. I was also given positive feedback from my group members about how it was a good thing that I had a stretched out warm up and cooldown, as that was a big part of the routine that helped them feel more comfortable. I also tried to change my routine to incorporate the principles of continuity, overload, specificity, and variety. To work on the principle of continuity, I decreased the duration of the breaks in the middle of each exercise, so that the exercise would be done in a rhythm. In the first situation, the breaks were all 30 seconds long, but after incorporating this principle, I reduced all of them to 20 seconds, as I felt that would be something that is more challenging for the members for my group, and it was not too challenging, like asking to move on to the next exercise instantly. To work on the principle of overload, I increased the time for each exercise, which means that the person doing the routine would have to do one exercise at the same pace for more time than they did before. The time the person would have to do push ups, situps, and planks, were all increased from 30 seconds to 1 minute, as I felt this would be something that is challenging if they were doing multiple sets of this, especially if it is someone who does not exercise on a daily basis. I worked on the principle of specificity by changing my exercises to make sure that each exercise is mainly working on one part of the body. I used 6 different exercises that challenged parts of the body such as the arms, core, calves, and lower body. I also used exercises that would be challenging to do for longer periods of time, as this works hand in hand with muscular endurance. Lastly, I worked on the principle of variety by using different exercises to work on different parts of the body, instead of using similar ones to work on just the upper body or lower body in general, I worked on 5 different parts of the body using 6 exercises, I focused more on the core because I felt that was a necessary aspect to work on for muscular endurance. The training method used was ME, which meant that it was a circuit with strength-based exercises.The feedback I received from my group members told me that adding these principles made the routine a lot harder for them, but it was still manageable and they felt that it had a bigger impact on their body overall.
