Nearly all of the research in this search says there is either no statistical difference in effectiveness or “The diminished force output suggests that the overload stresses required for strength training necessitate the inclusion of resistance training on stable surfaces.”
Hello Chris Lutz,
When is the last time a surfer went out on the waves with weights? Hmm, am I going to see a video of this now? Has anyone seen the new surfboard workout?
For strength gains we stick with stable surfaces; no circus acts, thank you.
For balance, we do unstable surface work without resistance.
That does the trick for us and no one gets hurt.
