So, I started training for tris almost one year ago. Never had any formal swim training/instruction. I've read a lot about technique and figured it can't be that complicated. So, I've spent the last year swimming about 2 days a week average. No consistent focus on drills, just hop in and churn out about a mile of varying intervals. After the first few months, I haven't gotten much faster. So, I'm giving in and going to focus on technique more.
Yesterday I decided to concentrate on a proper catch; hand entering the water just below the surface, reaching forward as far as possible with body rotation, keeping fingers together, slightly bending wrist, bending at elbow while keeping elbow as close to the surface as possible, pull through to the hip to complete the stroke, and repeat.
So, is it a good sign or a bad sign that I have quite a bit of muscle fatigue in my forearms? Or does that indicate anything about proper form?
