The key to cornering is the ability to match the lean of the bike and the lean of your body to the trail. At the heart of this is your ability to lateral hinge laterally at the hips – without this essential movement skill you will always struggle to corner consistently.
One of the best exercises I have found to train this lateral hip hinge movement is the Rotational Lunge with a sandbag. This exercise does a great job of building hip strength and power in a very unique way.
In this video I show you this exercise plus a few ways to advance the exercise as you get better at it. In the video I use the Ultimate Sandbag and highly recommend that you invest in one if you want to add sandbag training to your routine.
