It sits on the day uncounted until it is priced.
The Concept2 shows watts, so it is measuring real work rather than guessing. Take its calorie number and subtract what you'd have burned sitting there — 85 an hour. Walking and running go here too, from distance and time.
The Bowflex shows no watts, so its calorie readout isn't measuring anything — ignore it. Log the minutes and how hard it felt instead. Level and time get stored raw anyway, so after six weeks of weigh-ins your own levels can be back-solved into real numbers.
Pushups, pullups, weights. Sets, reps and load get recorded because progression is the point — but they add nothing to the day's burn. Deliberate undercount: you never eat back calories you didn't earn.
