They could be trim due to poor nutrition. May be their pay affords them just one poor meal each day.

@Angelica, if you consider the combined effect of what these people who walk daily, do, then we can account for fitness.

Watu wa mkono, kazi yao tunajua. Watu wa kufua...

Also, some of these walkers may not pass a basic fitness test.

Again, it's easy to forget that fitness is for doing something. One might appear to be fit when she's in fact, unfit.

Like Usain Bolt, he appears to be fit. Yet he's not fit for 100m dash, and neither is he fit enough for professional soccer. Currently, he's exercising for soccer fitness.

Walking is good exercise for a person recovering from sickness. But is it good for a 'householder'? If you do a white collar job, you drive most of the time, and eat 'well', then walking isn't the best exercise for you.

Why? Because being a householder demands a kind of fitness that walking alone can't support.

I do HIIT 3 times a week and walk 5kms twice a week.

Enough exercise for me.

You are advanced my broda. Hilarious that some think low impact cardio (walking) is "not exercise"

My HIIT comes from speed rope, 1 minute intervals 1 minute rest at maximum exertion till burnout. Fat torcher kabisa, that achieves 10 times more in 1/10th of the time it takes to jog gazillion miles. On the days I do weight training I skip HIIT and vice versa. Walking I'm trying to do every single day to burn those extra cals. My challenge as always has been limiting carbs. The most unhealthy foods are always the tastiest jameni. Speaking of walking, off I go!

Did some serious walking the past week, kept carbs low, have been keeping up the weight training and I'm seeing great results on the scale each passing day. Feeling like kevin Garnett right now. Youngsters may not even know who the kuyz is Happy workouts, rafikis!

I too do HIIT on Mon, Wed & Fri mornings. With no any other exercise apart from StanChart Marathon

I would want to build an active regime around my day-to-day activities. Like avoiding lifts, walking rather than driving. But that discipline is...

Speaking of avoiding lifts, haaaaai!! Jana I had a meeting in CBD and unfortunately the ka-office was in one of those old buildings. You know the ones. They have an inscription "Jagdesh House..1914" or whatever. Always pale blue or white and coated with thick CBD dust on the copings. Window panes have been painted over a zillion times to the point they have an unsightly crust that observes of antique buildings would describe as "having a special charm" just to mask its raw unpleasantness. Haiya, lift does not stop at 1st floor so you have to tembea juu. Auuii..steep as a nonsense stairs that strangely go four flights just to get to first floor. My usually well conditioned legs were on fire by the time I fikad the top. Bottom line, I need to keep going back to that building every time I am in CBD to get a quick 5 minute leg workout!

Si umekonda sana?

Not really but I'm doing good. Early October i was 92 but now I'm 85. By Feb next year I want to be 70.

Boss,unless you are under 6ft tall seems you are aspiring to be blown away by the wind! 70kg is "skele" territory, Jameni. I can barbell bench the equivalent of two of you easy at that weight. But if you are 5 ft tall then it makes sense.
