I finally got outdoors to do some exercise on Sunday. 40 minutes very gentle bike ride with Mr Steady. Then in the afternoon a 4 mile stroll with friends and dog. Tired afterwards but the cold is still hanging around and at my annual asthma review I was told to not exercise until well and rebooked to see the nurse in 6 weeks.
The only good news is that I have not put any weight on, but that will be due to a frequently disappearing appetite.
I only do around 30 -35 seconds for 25m and think that I have a steady pace, but have managed 3.8km in 1 hour 43 minutes. I only swim once a week at present and not too worried about getting much faster.
Any swimming drills are done much slower as I need to concentrate.
Having 20 lessons and 4-5 teachers I am not surprised you have not made much progress as each teacher will have their own way. Just concentrate on one aspect of front crawl and master that before adding another. Eg breathing, or the catch or the kick. It will finally click the same way as breaststroke has.
