https://community.usms.org/swimming/f/general/9287/kick-time-improvement-with-finsIs there a general view on how much kick times should improve when wearing fins? If they improve more or less than this is this a sign of any kick flaws? Thanks, Nen-USTelligent Community 12https://community.usms.org/thread/147018?ContentTypeID=1Tue, 06 Jul 2010 15:49:47 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:10ea1ac6-a547-4f99-956c-ad1d17ce8f68Former MemberWith fins I can flutter kick a 100 SCY in 1:05. Without fins, I would have trouble breaking 2:00.<div style="clear:both;"></div>https://community.usms.org/thread/146938?ContentTypeID=1Tue, 06 Jul 2010 12:43:16 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:b831a20c-4a1f-426e-90ae-0586aab38eedFormer MemberI don&#39;t disagree with the above. I&#39;m just curious how much extra propulsion fins typically give. I can kick hard for 100 SCY maybe 1:25-1:30 (I&#39;m not the best kicker, but not horrible either) and with fins I could go under 1:10. I routinely do 50&#39;s fast with a board and hold :28 on a :50-:60 interval.<div style="clear:both;"></div>https://community.usms.org/thread/146847?ContentTypeID=1Tue, 06 Jul 2010 11:52:06 GMT3187ac58-ba85-4314-b79a-c45cd885e09a:c8c82da5-2cde-4cfc-965c-6135ff0c4321Former MemberI don&#39;t disagree with the above.

Fins should be used as a training/strength aid. You may also gain &quot;some&quot; flexibility in knees and ankles and strengthen your core. As far as flaws, fins would mask them more than anything I would think.<div style="clear:both;"></div>
