In addition to the forward lunge (see the video here – ), the vipr can obviously also be used to load some side lunge patterns. Again, there are numerous variations that can be used, such as rotating with it, tilting it, ‘sliding’ it out laterally, lifting it, and again, each of these variations will provide a different challenge so you can look to experiment.
When rotating the Vipr, make sure you are controlling it rather than it controlling you! Movement wants to come from the hips, so work on your hip mobility, and knees, with the torso remaining strong.

You’ve seen players like Djokovic holding crazy positions and remaining strong. The variations on this exercise will help you do this.
