In the app I specified I’m in possession of an Olympic bar weighing 20 kg. Why does the app suggest warmup exercises with a bar weighing 15kg? For example push presses or rows. I think this is an error in the app. Also; I have fractional plates weighing 1.25 kg; but the app only takes one decimal. So I can only specify 1.2 kg for the fractional plates. I think this could be easily improved upon.
