how to run simultaneous commands

I have a bash script.

f1 () 
{ 
    for ((i=1; i<6; i++))
    do
        a=$(echo -e "\033[41m ")        
        echo -n " $a";
        echo -en "\033[0m";
        sleep 1;
        echo -en "\b";
        echo -n ' '
    done
}

f2 () 
{

    a=$(echo -e "\033[41m \033[0m") 
    echo -en "\033[5;50H$a"
    for ((i=1; i<6; i++))
    do
        echo -en "\b"
        echo -en ' '
        echo -en "\b\b"
        echo -n "$a"
        sleep 1
        echo -en "\033[0m"
    done
}

f1
f2

f1 shifts the object to the right; f2 shifts another object to the left;

what can I do to execute both functions at the same time, so that I see both objects move at the same time?

#this wont work
f1 & 
f2 &

Run them in background with parallel:

  #export functions so parallel can see them
  export -f f1
  export -f f2
  #run both functions
  parallel f1 f2
