It is definitely boring, at least initially.

Later, you can compare how you feel with previous workouts and notice differences in how you feel, challenge yourself etc.

You can consider the first few times to just be a benchmark. Another reason to not give 100%: You don't want to put the bar too high for the next times, lol

But it may still be boring so that's why finding something you like doing is important :)

I want to get into bouldering and climbing again. That was the most fun I had while exercising in my life.
