X-NUCLEO-IKA01A1 Electromyogram problem

Heys everyone,

I'm new to the ST Community, so hi ^^. Anyways, I'm working on with the X-NUCLEO-IKA01A1, and I'm trying to use the Instrumentation Amplifier that the X-NUCLEO Board has; therefore I went and looked for some examples to get me involved with programming with this board. 
I found out the STM32CubeExpansion_ANALOG1_FIR (STSW-OPAMP002) that had an example that has to do with Electromyography; opened, read it, and compiled it. No errors, but as I've read on the instruction manual for this demo, you have to calibrate, and whenever a movement is detected an LED will turn on. The thing is the LED is always on, and I think I'm not getting the correct data even though I'm connected, and everything is connected as should. 

(I'm thinking this because whenever I'm moving my arm that is connected to this, I'm not getting a lot of fluctuation in numbers as it should happen.)

Any ideas or suggestions to troubleshoot this?
