I don't feel it's reasonable at all

I am new to the app , balanced burn plan, age is 32 .
I excluded some exercise to avoid any unnecessary knee pressure such (jumps , standup , knee jump, split lunges) I have issue in my knee and I am recovering so not all all this things I can do

when app asked about my fit level I choose low one , because I want to gradually increase my (stamina , power & technique)

now the issue , some times app give me normal exercises which is very easy

or it go to max hard

for example today , I have 50 burpees , 50 sequat , 50 situps

I keep telling the app burpees is hard
situp is hard

why he cannot give normal core exercise to develop the strength and stamina than increase.

another example: side twist , this one I am not able to do , cannot balance properly , so app give assisted side twist , for one time than again ask to do 7 normal high side twist , I mean what on earth , I barley was able to do 5 assisted side twist , how come he ask to do 7 normal one

I don’t feel the app building things gradually at all,

can anyone suggest what I should do in the configuration or options to adjust that?
