How you use it will depend to a large extent on what it was designed for. If it's a steep board with relatively small holds you might find you can only do a few moves at a time. That will be great for getting stronger. You make up boulder problems with moves that are challenging. It won't be so good if you want to get more endurance.
For endurance you want to do longer problems and lots of them. Try not to get completely pumped by going to failure. If you do you'll just have to wait longer before you can go again. But if the board is too steep or the holds are too small it might not be possible train endurance on it.
