There are many potential applications with using the duffalo bar. If we had to narrow them down to our top three they would be 1. To relieve the strain put on joints when in a back squat position. 2. To create a better training stimulus through a larger ROM when performing pressing variations. 3. Increase the loading potential of particular squat variations such as the front squat. There's significantly more applications for it but these three are amongst the most important.
