Completely.
Before you start the game, it will as for your age, current fitness level, and how hard you desire to workout. Then it will give you a push/pull test and a jogging test that will determine how well you've got to do each exercise.
It's shockingly accurate, and I felt like my jogger was going at the exact pace that I was in real life.
The next day, evidently, the game asks if you'd like a harder, easier, or similar workout. It's super slick.
It checks in with you every day and asks how the previous workout went. It will allow you to adjust the difficulty as you go.
It gives you a recommended level based on some questions. After you finish a workout / level and you check your heart rate, it will ask you if you want to go easier if you're too high. Assume same is true if it clocks you in too low.
Ah sounds like my worries are unneeded if it not only checks at the start, but in between sessions also. Thanks for the information! I'll keep an eye on it, and either pull the trigger before GCU expires (or maybe a BF deal will pop up).
