Hey Justin,
I’d also look at just adding in some simple drills to be done as part of the training experience. For example, 5 min of jump roping sold as foot health, or springyness training will do it. We did a post about Zhang Weili the MMA fighter on insta about her foot strength/fascia drill she does. This would be easy to add into the system. For your older folks (me) I’d add in some collagen supplementation as well.
Crazy how tricky this is!
