How do I enter my workout with trainer ?

Mina32719

I workout with my trainer abt 2 to 3 times a week, but its hard to keep track of what he does, so I usually ask him how many calories i might have burned. But I am having a hard time entering those calories burned in this app.
PLEASE HELP !!! Is there any way i can just add calories in strength training w/o adding what i did?
