Hi, welcome to the forum!
Once I asked here if anyone else thought that the programmes were too upper body focused, so my conclusion is that they vary per user. 
A few parameters affect your workouts: the journey, the number of scheduled days per week, the equipment you specified, the exercises you may have excluded, the level that Coach thinks you have.
Iāll take a guess and say that Coach is trying to build up your strength and doesnāt know your level fully yet.
I agree it is a bit confusing. Once you know the logic, it makes sense, but the truth is many people donāt know it and may get demotivated before the Coach adapts.
Things you can try:
- On the Coach screen, find Single exercises and perform and log some upper body exercises (e.g. pushups), so Coach learns that you can do them
- Next time you do a Coach session, first click the āAdaptā button - I want to exclude certain body areas - legs. Try playing with the Adapt option until you get a workout with upper body.
