Unless you make a real effort to book some time alone for a gym session or whatever activity floats your particular boat, you need to somehow exercise with the little ones in tow (literally in this case).
Yesterday the sun was shining and we were full of the joys of spring, so we dug out our bikes from amongst the spiders in the shed (I say we, my husband regularly cycles so I shouldn't tar him with the lazy brush), pumped up the tyres and hit the road. The boys rode in their bike trailer for the first time (exactly the same as the picture) and they absolutely loved it. There were whoops of joy for at least the first half an hour and, as we sped through puddles, everyone was terribly happy.
I definitely felt the burn in my legs and enjoyed pushing myself as we tackled a few hill climbs, deep mud and stones on the beach (I should point out that I was not pulling the trailer! I don't trust myself going round corners and my husband is very capable on the road.) We took around an hour to ride a few miles, with a couple of stops to check the boys. There was an obligatory tea and biscuit stop at the country park before we headed back, which took another hour or so. It was a perfect afternoon en famille!
So, how much can one expect to burn on a 2.5 hour bike ride, across multiple terrains, such as the road, the beach and the park?. Having done a little research it seems that you can burn anywhere between 5 and 20 calories per kg of body mass, per hour. This does depend on whether you're pootling about or busting a gut - two official technical terms for different levels of effort. So, I reckon that in total I burnt about 500 calories during our excursion. The thing is, when you're enjoying yourself so much and spending time with your favourite people, it doesn't seem like a chore.
Positives: Family fun, decent calorie burn using lots of muscles and a good dousing of vitamin D. Also, the boys went straight to bed, worn out by all the fresh air and slept for 12 hours.
Negatives: A bit saddle sore this morning and there was lots of mud, all over the place, in the house. Ho hum, that's what you get from being 'outdoorsy'.
