Expedition Fitness: Is There Such a Thing? (1)

Do expeditions require a special kind of fitness? Or, to put it another way, is there a type of fitness you or I can have that would help us cope in an Expedition?
This question, as it stands, is too generic to be answered properly. Let’s break it down a little.



Fitness
The first thing that strikes me is that fitness can be physical or mental. To simplify things for this post let’s focus on the former.
So what is physical fitness? In his excellent book “Get Fit Not Fat” Greg Whyte lists four components of fitness:
That’s a nice and simple definition and can serve as a good basis for an exercise program. But is it complete?
In its October 2002 edition, The Crossfit Journal defines fitness as follows:
  1. Cardiovascular/respiratory endurance - The ability of body systems to gather, process, and deliver oxygen
  2. Stamina - The ability of body systems to process, deliver, store, and utilize energy.
  3. Strength - The ability of a muscular unit, or combination of muscular units, to apply force.
  4. Flexibility - the ability to maximize the range of motion at a given joint.
  5. Power - The ability of a muscular unit, or combination of muscular units, to apply maximum force in minimum time.
  6. Speed - The ability to minimize the time cycle of a repeated movement.
  7. Coordination - The ability to combine several distinct movement patterns into a singular distinct movement.
  8. Agility - The ability to minimize transition time from one movement pattern to another.
  9. Balance - The ability to control the placement of the bodies center of gravity in relation to its support base.
  10. Accuracy - The ability to control movement in a given direction or at a given intensity.
A more comprehensive definition. But it seems to me that a definition of Fitness should be relative  - not absolute. Relative to the requirements, stresses and pressures placed upon you by the environment.
I may be fit for one thing but not fit enough for another; I may be fit for playing football at home but not for hauling a sled to the South Pole. Or the other way around.
And what are the demands placed upon you by the environment on an expedition? Well, that depends on the type of the expedition.



Expeditions
Up until recently the term “expedition” was used almost synonymously to “Exploration”. These days the same word tends to mean different things to different people: from a gap year adventure, to a tough trek, to a high mountain climb.
My definition is as follows: An expedition is a physical and mental challenge in a remote area with a definite purpose.
So this narrows it down a bit and leaves us with physically challenging activities in remote areas: deserts,

jungles, ice caps, mountains (deliberately ignoring underwater expeditions here).
Each one of these environments would pose different challenges to the adventurer: heat, cold, humidity, wind, altitude etc. In addition the purpose of the expedition may impose challenges of its own:

An expedition to ski across Greenland would pose different challenges than one to cross it with dog teams.

An expedition to cross a jungle would be very different than one to cross the same jungle but living off the land without external food or water.

An expedition to run across a desert with a support team and one to walk across it solo and unsupported are two very different propositions.

All these factors will affect training regime to be followed in preparation for the expedition. In a later post I will describe my approach to Expedition Training.

Get a Grip: Warm-Up (2)

My body’s response to any particular work-out programme varies with time. Assuming I start with a new work-out I always go through the following phases:
  • Shock. The body, faced with a new and unfamiliar task, struggles to cope. Aches and pains and the realisation that I wasn’t as fit as I thought. This period is brief and I take it very easy.
  • Horror Adaptation. Performance increases rapidly. This is the most dangerous period for getting injuries because it is difficult to tell if I am overdoing it.
  • Plateau. Performance remains flat. It is possible to squeeze out some more performance by making small changes but essentially my body is now fully adapted to the workout and considers it “business as usual” – no need to improve further as it is perfectly capable of meeting the current level of demand.
When I reach a plateau it is time for a change. And because these changes are the rule rather than the exception I feel it is very important to
  1. Have a repertoire of different exercises for any given fitness “target”,  (e.g. a target could be “shoulder strength”)
  2. Make sure my exercise regime includes a variety of elements like running, weight lifting, cycling, so that if I hit a plateau in one of them I can shift my focus on another for a period.
Anyway, the topic of this post is to describe some more of my grip warm-up exercises. So here goes:
This is an exercise I learned many years ago. I basically open up my hands and then make them into fists as fast as I can for as long as I can. It doesn’t sound challenging but believe me it is.

When my hands start burning I may move on to using a light weight to warm up my thumbs. I use a plate with a “lip” for this so that I can hook my thumb under it.

I make sure I let the weight drop all the way down and lift it all the way up.

Sometimes I use a bar for warm-up. An Olympic bar, like the one in the picture, is heavy enough (20kg) to be used without additional weights for warm-up.

Get a Grip: Warm-Up (1)

My first introduction to hand strength was when I, as a 13-year old, joined an Olympic wrestling club. Grip strength in Olympic wrestling is massively important and the coach used to start each training session with a good grip workout. Often my hands would be so exhausted after a session that I would get cramps in my palms during the night.

A strong grip is always an advantage as it improves control of hand tools and is a key component in sorts as diverse as golf, wind-surfing, skiing and climbing.

In the jungle a good grip is necessary when moving outside established footpaths, where you have to hack your way with the machete

In this series of postings I will be showing several hand strength exercises that I use and have had good results with.

I will cover warm-up, stretching and main workout.

Warming Up

Normal Grip - Open.
As with all body parts I always try to warm-up before my main hand work-out. One of the tools I use for that is a pair of hand grips. People often don't realise how versatile these things are and that they can be used in a variety of ways to achieve the desired result. 
Normal Grip - Closed.
I start by using a "normal" hold using my whole palm and do a few reps with each hand. This exercise favours the fingers further from the thumb so I then reverse the grip to work  index and middle fingers. 
Inverse Grip - Open
Inverse Grip - Closed.

I then move on to work the thumb itself. Note the modified grip I use.

Thumb - Open


Thumb - Closed.






Then I begin to isolate the top two or bottom two fingers like so:

Top Two fingers Only - Open


Top Two fingers Only - Closed


Bottom Two Fingers Only - Open

Bottom Two Fingers Only - Closed.
There are different "strength" hand grips on the market and I make sure to use the appropriate strength for a warm-up, i.e. not too challenging.

Sponge Cake-Fuelled Madness

Today it was tyre-pulling day. For those not familiar with the term this means attaching a bunch of old tyres to your person by means of some kind of harness and rope and dragging them behind you to the amusement of everyone around you.

Here's a car boot full of tyres.





Today the program included

  • Running an 8k lap cross-country without any tyres for a warm-up.
  • Running another 8k lap dragging one tyre.
  • Dragging three tyres for an additional hour.
At the end of each lap I took a break to drink lots of water.

Then there was the small matter of the sponge cakes...




Now don't get me wrong - I normally don't touch the stuff. However, during long workouts I need something to get my blood sugar up; and boy are they good for that!

Tyres almost ready to go.


Here's where I run.



I forgot to mention I dragged them barefoot!



Back for more cakes!
