I am amazed at hour a 45 minute walk once a day can speed up your metabolism and reduce your bodyfat. Not a stroll, but a reasonably energetic walk. It doesn’t need to be stormtrooper fast but somewhere inbetween a stroll and a speed walk.
I can assure you 45 minutes x2 per day will leave you tired and also losing weight at a rate of knots.
I aim for 10 x 45 minutes per week now. And it works. Compared to cardio 3×45 minutes per week, it outpaces that considerably. There is no way I could physically do 10 x 45 minute cardios per week!
So walk it off….constant pace, religous schedule.
