Rebuilding Your Fast-twitch Muscles Doesn’t Require Fast Movements
Rebuild your balance in 2 minutes daily
We’ve all noticed as we age that we become a little less steady on our feet. This loss is due in the main to the deterioration of our neuromuscular capability to balance. But our fast-twitch muscle responsiveness — or lack thereof — also plays a crucial part.
When we lose balance our fast-twitch muscles act quickly to steady us and put us back into balance. If they are weak, then we potentially take a fall.
There’s good news. You can rebuild your fast-twitch muscle capability with less effort than you might have imagined.
Our fast-twitch muscles act first to prevent us from falling
I’ve often mentioned how muscle weakness and loss of muscle mass really are a root cause of lack of independence, lack of mobility, an increased likelihood of falling and living five years less.

Some things are not all that they are cracked up to be - especially regarding fitness and exercise advice. Balance is…
Our fast-twitch muscles help prevent us from falling, and this speed component of muscle power seems to be an Achilles’ heel for seniors.
There is a good reason for this. Fast-twitch muscles (our “power muscles”) atrophy at a higher rate than our “endurance and strength” muscles. (The latter atrophy at the rate of 3 to 5% per decade after age 30, if you are inactive.)
Power declines much faster than strength
Power declines at a rate of 3–4% per year in older people and this is detrimental for everyday activities such as climbing stairs.
What is power? Think of it this way — a bodybuilder has strength and bulk, an Olympic powerlifter has to have strength and power — hence the name.
To accelerate a massive weight off the floor requires power. To then hold it up off the floor requires strength.
The challenge for older people wishing to rebuild their fast-twitch muscles is that many of the prescribed exercises are very often too intense.
It’s generally thought that you need fast reaction exercises such as plyometrics, to rebuild fast-twitch muscles.
This is not the case.
Plyometric exercises include jumping onto boxes, star-jumps, burpees and jumping lunges, for example. These are intense, and the risk of losing balance is relatively high if you are starting and have poor balance.
Luckily, there is a long-forgotten but effective alternative style of exercises which are effective for fast-twitch muscle development.
There is a much less risky alternative
You may have heard of isometric exercises. While “plyo” means short — which is usually taken to mean jumping — “iso” means “the same”.
Isometric refers to the tightening of a muscle group without changing its length — in contrast to when you do a dumbbell curl or a squat, for example.
In the 60’s, isometric exercises were a popular trend, before Jane Fonda became a fitness superstar with her workout CDs. Advocates such as Victor Obeck appeared on TV breakfast and radio talk shows across America.
Despite being out of fashion, isometric exercises are still very effective at building muscular strength and endurance, and power — meaning the fast-twitch muscles. That’s why athletic coaches still prescribe them.
Being fast-twitch muscle only means that it is the fastest to fire and the fastest to fatigue. Trying to build that capability by moving fast works your momentum much more than your actual muscle. This is why isometric exercises are a very good choice for building fast-twitch muscle.

Isometrics are intense, low-risk exercises
The difference in which muscle fibres you build comes not from your training speed, but your training intensity.
With isometrics, you create intensity without the risk of injury from fast movements or from potentially falling as you might during during plyometric jumping exercises.
This makes isometrics exercises a perfect option to rebuild your fast-twitch muscles.
Four isometric exercises
By doing these isometric exercises you will reinvigorate the neuromuscular pathways from your brain to your muscles. This is a vital contributor to improving your power and reaction times — meaning, that will you be more likely to recover quickly from a loss of balance.
One of the four exercises is an arm exercise since quick actions with your arms can help you regain balance. There is one for your lower back, as it is a crucial link for stabilisation, and two for your legs.
General isometric exercise instructions
For all of the exercises apply the following method:
- Warm-up a little with some loose movements and swings;
- Hold the maximum contraction for 6 seconds;
- Count the 6 seconds using your phone or a clock or a time-honoured method such as counting “1 Mississippi, 2 Mississippi etc.”
- Rest 15 seconds between exercises;
- Breath normally during the contraction period — don’t hold your breath;
- Do each exercise only once;
- Do not do them more than once per day.
#1 Isometrics for the arms
Lie on the floor, face down. Extend your arms straight out to the side. Now press down.
#2 Isometrics for the lower back
Against a wall, stand one step away and reach up with your arms extended, palms forward pressing on the wall. Press your palms straight ahead into the wall as strongly as possible and fell the pressure coming down through your back.
#3 Isometrics for the legs
3.1 Knee squeeze
Assume a sitting position on a chair with your feet shoulder-width apart, placed flat on the floor. Place your right hand outside your right knee, and your left hand outside your left knee.
Now, attempt to spread your knees apart while applying counter-force with your hands and arms. This is a squeezing-out exercise for your thighs and hips.
3.2 Foot squeeze
Seated or lying flat, extend your legs and press your feet against each other. If you prefer, place a pillow or cushion or roller between your feet. This is a squeezing-in exercise for your thighs and hips.
These exercises will take you 6X4 seconds, with 15 seconds between each, once each day.
That’s less than 90 seconds daily, with almost zero risk of injury — unlike plyometrics.
How to test your progress — at home
You’ll find that by doing these consistently, daily if you can, you will soon start to notice an increase in the strength of the parts you are exercising. Give each exercise all that you have — push as hard as you can.
You can test your progress for yourself.
Stand by a wall and take a little jump, or reach up, an touch as high as you can. Check every two weeks and see how you are making progress. Like a child growing, make a little dot on the wall to track your jump-height — make it fun.
Good luck. Let me know how you go.
