dumb trainer, dumb asian..........I'm not seeing a problem here
You have a point but let me explain.
A dumb trainer allows you to become lazy and ease off when it starts hurting. If you don't have better than average mental fortitude, towards fitness goals, you start have sub par workouts.
A smart trainer doesn't give you a choice. It follows the workout you load or the course you picked and your legs, heart and lungs have to keep up.
In real life, if you give up going up a climb you fall over, on a smart trainer you can pedal faster or slower but the resistance won't change; your animated you will stop and unclip if you completely stop.
On a dumb trainer you can just pedal slower and have less resistance. Human nature tells you to go easier when it gets hard so take it out of the equation.
