Here is the info on Scrubbing:
- Yes, scrubbing will effectively impact the final results. If you scrub forward in time, it will shorten the workout time and any intervals/rests that you skip over. If you go backwards, it overwrites the previous efforts and “loses” that data.
- If you have time and know before, it is possibly best to pick a more desirable workout. But, if you are mid workout and decide you need to scrub. It is likely best to just do that. Each situation will vary as to the best move to make.
