I can just paddle as long as I want on one side because the LOAD is not on my JOINTS .. it's on my CORE ... the Limitation is my average fitness right now .. LEARN to CHANGE Gears .. Sprint Burst .. RELAX ... the only time my joints hurt is when I sleep at night ! - SOFT CATCH means you can MOVE the BOAT , NOT Chip/HAMMER the Water and transmit the impact force to all your JOINTS MYTH vs TRUTH ... GENERALIZATIONS vs SPECIFICS Little Knowledge is Dangerous ... THINK before you ACCEPT Blindly no matter who's telling you .. including ME .. Does what I say makes send Physics wise and Bio - Mechanically ? How do you INJURE your Shoulders ??? - LEANING your ENTIRE WEIGHT on the JOINT instead of using your BIG Back, Lat & Leg muscles .. Bad Techniques CAUSES Injuries of ALL KINDS of JOINTS As they say .. a Bad Carpenter always blames his Tools ( even though they are best tools on the planet ) .. A Good Carpenter can build ANYTHING perfectly with Good Tools .. FACT !
