I watched your video yesterday and found it very interesting. I tried it out with a broomstick (no load -- friday is shoulder day) and it makes sense to me to vary the movement.
Question; would you recommend to always do shoulder presses this way, or only occasionally?
If you are not a big fan of lifting heavy weights overhead, you can use it always. If you a big fan of lifting heavy weight overhead first you need to keep your shoulders healthy and flexible with this exercise. After the main workout, you can use this exercise to keep your shoulders healthy and balanced.
That makes sense! Great input. I will try this out properly on friday, as part of my shoulder routine.
Have Fun ;)
