Reducing tendon / hand pain to optimize training
I feel like this is a hugely underlooked thing that makes an incredible difference on how many reps you can do. The first thing that gives out for me is always my wrist and forearm area especially during heavy bench press or such, I always pad the bar and wrap most of my forearm and wrist/hand. You end up feeling the same amount of pain but it's in the muscle as opposed to the wrapped areas.
It isn't just training either, I notice this helps in pretty much any physical activity in general, be it working or whatever, there's a much better mental connection.
