LabVIEW
How to do this in Labview ( pushing a button)
Depending on how your buttons work, I am picturing a simple DIO board that can control some FETs or relays that act in parallel with your actual buttons. Then you just toggle your digital line to simulate pressing of your button.
Sorry if my question sounds confusing and thank you so much for all your responses so far
to clarify. This is our exercise machine console
We wanted to reprogram it but scifit bike company doesn't share the schematic of the circuit board . So we are trying to find a way to increase or decrease resistance ( so the up or down button be pushed ) at certain T period . That's why we thought maybe we write a lab view code then somehow make it run on our program?!? Any idea how ?!!

What you need for the first step, LabVIEW has nothing to do with it. You want to programmatically-physically push the up and down arrows on this device, yep? I guess this device does not provide any communication interface or digital/analog input, so you need to go in a "brute force way".
You have two main options, first is non-destructive, the second is:
- Do a physical button push with a solenoid actuator, pneumatic actuator, or even a robot arm. The "thing" what will push the button physically, will needed to be interfaced with LabVIEW using an available method, depending on what kind of hardware you have.
- You need to open up the that plastic box shown in your photo, and figure out how the wiring is done toward the button. If you are lucky, there are simply two wires going to the button, and you can test its functionality by simply connecting/disconnecting them. If you see that this simply works, you only need a programmable relay switch to do the action. All depends on your budget or the available hardware what you already have. Whatever relay switch you use, you need to connect it to your PC in order to program it with LabVIEW (timing switch ON/OFF, etc.). NI offers such hardware, but there are other cheaper alternatives too. Like this, with USB interface and it has two switch relays: http://www.yoctopuce.com/EN/products/usb-actuators/yocto-relay (you need to check the available programming libraries before you buy some like these, even if there is no dedicated LabVIEW driver, you can work happy with a simple command line option too).
Is this a joke? 
How do you expect that by only looking at a photo I can help with the wiring? I even cannot see where those front side buttons were connected. Sorry, but you need to seek an IRL help...
