I’m having a tough time trying to program 2 fsr sensors
Call your second FSR "fsr2" connect it to analog pin A1 and add to your existing code. Sort of like this:

int fsrPin = 0, fsr2Pin = 1;     // the FSR and 10K pulldown are   connected to a0
int fsrReading, fsr2Reading;     // the analog reading from the FSR resistor divider

void setup(void) {
  // We'll send debugging information via the Serial monitor
  Serial.begin(9600);   
}

void loop(void) {
  fsrReading = analogRead(fsrPin);
  delay(5);
  fsr2Reading = analogRead(fsr2Pin);


  Serial.print("Analog reading = ");
  Serial.print(fsrReading);     // the raw analog reading
  Serial.print("\t");
  Serial.print(fsr2Reading);
