Ever since I had started swimming 3 weeks ago, I had observed my body is responding to the exercise much better than before. This is despite after reading about swimming burns less calories, or how it is less effective than running in achieving weight loss.

Apart from feeling the ache of my body muscles all round after a swim,  versus the feeling of ligament strains after a run, I thought I have become leaner after 3 weeks if daily swim, at least psychologically.

Here’s my reasoning; It is an established fact that exercising burns different source of our body “fuel” (fat, carbohydrates, protein, etc), depending on the zone that our heart is exercising. At aerobic zone, our body burns more calories than exercising at fitness zone, while consuming a more balance percentage of energy source between fat and carbohydrates.  Unless I am on low carbohydrates diet, aerobic zone is the most effective weight loss zone.  Having run for 9 months, I know it is not an easy to keep to aerobic zone throughout the one hour of running, probably due to the loss of body fluid. On the other hand, I noticed that I can keep to the aerobic zone consistently regardless of whether I stick to a 30 mins or 1 hour swimming session.

Back on swimming, I am never been a natural swimmer from the onset. I do not feel comfortable when in the water, even when I could stay a float or swim. For a long while, I would have struggled to complete a 100m  freestyle, let alone a long distance freestyle swim. In the last 3 weeks of swimming, I have been doing one lap of  freestyle with one lap of  breast stroke routine for my swim. The breast stroke is more like a rest stroke for me to catch my breathing before doing the next freestyle lap. But 2.5 weeks of consecutive swimming seems to have paid off.

On 12th September, I managed to stretch my swimming distance to 2.5km, albeit with the alternate strokes method. Despite four consecutive days of 2km (with one of them being 2.5km) swims, I did not feel any more fatigue, unlike a week ago. While I only completed a 1.5km distance on the 5th swim day (I had originally planned for a 1km swim) I actually completed a 40 continuous laps (or 1km) of freestyle swim. It is simply amazing that after 40 years, I have finally achieved this feat.

With all said, I figure that I should try and improve my strokes so that I can breathe on the alternate sides. That would probably be my next goal while continuing to stretch my freestyle swimming distance. In the meantime, I am looking forward for my next run (target to be a week later), as I am confident that 4 weeks of daily swimming should bring some positive impact to my running sessions.
