Part 2 How to get / keep fit.

1. Walking

walking as excellent exercise for fitness

10,000 steps a day is a recognised route to fitness. Everything counts, even the naughty visit to the safe wherein the chocolate hides!

However, recent studies highlight the benefits of intensity. 3 times 10 minutes a day, 5 days a week is plenty. Fast enough to make singing very difficult.

2. HIT high intensity training

a. Exercise Bike


The most surprising example of this uses an exercise Bike
H.I.T. high intensity training on bike

3 times 40 SECONDS a week. That's 40 seconds Monday, Wednesday and Friday, for example. This has to be as strenuous as we can manage, and it depletes the glycogen from our LARGEST muscles, thighs and buttock, which respond by taking sugars from our blood, where it can contribute to obesity, diabetes, heart and circulatory illness.

The benefits are similar to spending 45 minutes running.

The same results can be achieved without an exercise bike, indeed with no equipment at all.

b. DIY FIT exercise at home


2 minutes gentle warm up,
1 minute star jumps,
star jumps exercise, DIY F.I.T. exercise at home

1 minute squats,
1 minute running on the spot

1 minute squats,
1 minute star jumps.

Brief rests are okay between each stage.

3. Muscle mass


As we get older, muscle mass decreases, which can led to all sorts of problems, some obvious, some not.
muscle mass sustained by weight training

The remedy is simple. Weight training:
weight training to preserve/recover muscle mass

3 sets of each exercise, twice as week.
Even when we are resting, muscles take sugars from our blood with the health benefits mentioned earlier.

An earlier documentary from BBC showed the energy used in each member of a family over 2 hours. The woman doing housework used more then the young adult who spent 20 minutes on a bike.

The 14 stone, muscular man who lay on the couch used most.

This I not an advertisement for the couch.

4. Motivation.


The experiments showed that willpower is fragile for most people.
The gym is soon skipped if the chocolate biscuits are waiting at home... So sleep them in the locker at the gym.

Exercise will be regular if its at a pleasant, convenient, companionable venue. The venue, which can be home, could contain rewards.
stress on knees while walking or running

Running, and energetic walking, puts some stress on the knee and hips joints, but this can stimulate blood flow into the cartilage, which speeds up repair. Runners are less likely to get arthritis as they age.

Overall, the most rewarding and enjoyable aspect of exercise is the variety.

5. Mental health and exercise.

endocannabinoids synthesised in human brain, more-so with lengthy exercise

Lengthy bouts of aerobic exercise produce a euphoric state known as Runners High.
Both endorphins and endocannabinoids are synthesised in the brain.

Dance is very good exercise, especially for the brain
a. Short term memory
b. Balance.
Both of these faculties need preserving as we age, particularly as longevity becomes more common.
Dancing as best exercise for fitness, all-round health

Spatial awareness, rhythm and music are all providing a pleasant workout for our brain when we dance.


End of documentary.

6. What Next could we try?


The activities commonly described  as anti aging do not seem to mention balance and reflexes.

Roller skating, mild gymnastics, and a reflex workout like an arcade or racing game. Not advised for addictive personalities!

  2. It's very hard to stick with an exercise program. I've attempted many..many...many...many of them. I've settled with gardening being my exercise. Something i enjoy.
