The 24 hour, 100 mile race are done by some runners who train heavy only
once a week. If you walk 2 miles a day, 6 days a week for a year and then
walk 5 miles, you'll be dragging your butt and if you try 10 miles, then
you'll need someone's help. In the Army I could do 50 pushups 10 times a day
every day, but I couldn't do 60 pushups. Any comments would be appreciated.
A simple reliable method of exercise to get you fit enough to do
something is simply to do it, or as much as you currently can, rest
until you feel fine, then try again. Long unused muscles can need a
week to recover, whereas muscles used to training can recover in a
day. Evolution has seen to it that this method of doing your best to
do your best works pretty well.
It gets more complicated if you're trying to do gym-type exercises to
prepare you for some outdoors activity, because it's hard to exercise
all the needed muscles in the right proportions and in the right way.
For general home-based leg conditioning to walking up hills I rather
like "Hindu squats", i.e., repeated non-weight-carrying deep squats
down to bum on heels, pause to avoid cheating by using bounce, and
then up again. Repeat until you fall over :-) But if trying one of
these deep squats causes knee cracking, pain, or pretty serious
exertion, don't do them until your knees and legs have got a lot
stronger. If you have unfit knees these squats will rapidly wreck
them. Stairs two at a time are good for unfit knees.
If what you're after is developing as much strength or as much
endurance as possible in the shortest possible time, then it gets even
more complicated. There's a lot of variables to play with, intervals
between exercise sessions (e.g. 12 hours), periodic rests (e.g. two
days off a week), what proportion of maximum strength to repeat, and
for how many times. People vary widely in how they respond to
training, and this also varies as you age, and with your degree of
fitness to start with. I suspect the optimum training schedule for
fastest results needs to be tailored carefully to the individual, and
that indivual's current state.
Being somewhat housebound at the moment, I'm doing some home-based
exercises to the point of exhaustion and keeping a log of dates,
times, and reps. I've collected enough data on pullups to start trying
to curve fit a mathematical model of my own muscles' behaviour. When I
was a young fit climber a hundred years ago I don't know how many
pullups I could do because I got too bored counting them. I was
embarrassed to discover a few months ago that I couldn't even do one
from a completely straight hang, all I could do was twitch! So I
decided to find out how trainable my ancient muscles still were by
trying to train these thoroughly degenerate pullup muscles.
My doctors tell me that at my age I can't expect much. I do like it
when they challenge me like that :-)
So far I find I need 5 separate contributory functions in order to
calculate my strength at a particular time given a timed history of
previous maximum exertions.
These functions are:
A time of day cycle, with a maximum around noon.
Fatigue, negative, with a half life of about 2 hours.
Strain, negative, with a half life of about three quarters of a day.
Muscle training, positive, with a half life of about seventeen days.
Muscle growth, positive with a half life of about eighteen months
(there's not enough data yet for this last to be more than a fair
guess).
There's probably also a muscle training limit which I haven't got near
enough to register yet, which when reached will slow progress to the
muscle growth rate.
I find doing all this work keeps my brain fit :-)
The arms are doing well too. It took a while to get up to one pullup,
but once there things started moving, and in the last month I've gone
from one to four, and the rate is picking up as I discover what
schedule gets the fastest results.
So my general recommendation to anyone wanting an optimum gym-type
exercise schedule is to keep records and devise your own :-)
