Moshi Moshi!

I had planned to do a detailed review of the Landice L7 Executive treadmill today, but Mrs. Sensei has laid down the law and I only have a few minutes to post a review on this fine July 4th holiday — the DOJO itself is empty and all of the other senseis are off work and at home enjoying their families. Look for the full review tomorrow, but for today enjoy a quick rundown of the differences between the numerous models of Landice treadmills out on the market.

If you’vee spent time looking at Landice treadmills then you’ve probably noticed they have a large number of units available and the differences between them aren’t always as obvious as they should be. Here is a guide to comparing the different models, full commercial and light commercial.

At each level (L7, L8 and L9), the only difference between a Pro Sports Trainer, a Cardio Trainer and an Executive trainer is going to be the console. The Landice Pro Sports Trainer Treadmill has the lowest end, basic display, and the Landice Executive treadmills have the highest end (really spiffy, if you ask me) displays. The difference in the consoles is very obvious upon viewing.

The differences of each Landice treadmill level (L7, L8 and L9) is going to be the size of the rollers and the length of the deck. The higher the number, the heaver and larger the rollers and the longer the treadmill deck.

The LTD versus the Club style is an easy one as well. LTD means the unit is light commercial and Club means the unit is full commercial — meaning it is rated to run for a higher number of hours per week (full commercial usually means 100+ hours of use per week). The LTDs come in 110v and the Clubs in 220v or 110v. If you’re using a Landice Club treadmill in your home, make sure to request 110v or you may not be able to run it properly.

And there you go, the mystery of the Landice treadmills is solved!

According to scientists, there are three causes of alopecia in either men or women.

Too much DHT
Pseudo-oestrogen chemicals
Lack of vital nutrients

DHT
Free testosterone is broken down into DHT (a more potent form of testosterone). This chemical binds to the hair follicle receptors blocking vital nutrients from accessing the hair. The hair becomes miniaturized and thin and eventually dies. It is what’s called the “peach fuzz” look on young men with hair loss.

This is why eunuchs never had any hair loss which got Plato wondering. It is also why only men get male pattern baldness and women don’t. Hair loss in women is more evenly distributed with a thinning over the whole scalp. Also, effective DHT inhibiting treatment was only effective on young men with hair loss and not older men or women. Excessive DHT is therefore not the only reason for losing your hair.

PSEUDO-OESTROGEN CHEMICALS
It is normally unheard of for women in China to get hair loss at any age. Over the last 20 years increasing number of Chinese women in the industrialized areas of China are experiencing hair loss. This has been put down to chemicals form the industrial process which mimic the chemical effects of oestrogen. These pseudo-oestrogen chemicals bind tighter to the hair follicle receptors than normal oestrogen does, starving the hair follicle of vital nutrients, similar to the way DHT does.

Also, this seems to the reason for hair loss in obese men. Fat cells in obese and balding men contain more of the enzyme aromatase (responsible for converting testosterone into oestrogen). Also bacteria in fat cells produce oestrogen-like chemicals.

LACK OF VITAL NUTRIENTS
The hair needs a variety of nutrients to sustain itself. The theory is that both DHT and estrogen-like chemicals block the hair follicle by binding to it too tightly. Even without these chemicals, a person lacking in these nutrients will experience hair loss.

There have been experiments on mice which show the effect of a deficiency of certain vitamins or minerals. Scientists knocked out the genes in mice responsible for the regulation of the hair and scalp. These genes are in turn normally regulated by vitamin D. The result was rickets and hair loss with dermal cysts appearing quite early on. When scientists injected naturally “nude” mice with vitamin D, they started sprouting hair at an alarming rate.

It has been shown that copper and zinc, if lacking together, increase a loss of hair. In fact, a copper peptide was shown to induce hair growth in the skin around the wound of a person. The copper peptide was first used as healing accelerant.

For women, a lack of iron and the essential amino acid L-lysine has been associated with losing one’s hair. This therapy has proven to be very beneficial for women who are losing their hair.

The lower body contains some of your biggest muscles which are capable of bearing significant weights. The temptation for beginners to go for broke by performing heavy squats should be resisted. To begin with you should concentrate on building the muscles safely by using machines that isolate muscle groups. The squat is an excellent compound exercise that trains numerous lower body muscles but it is one you should learn properly after spending three months strengthening the individual muscles that will be utilized later.

The muscles of the lower body can be divided into five groups:

1. Quads – this is the big muscle group consisting of four muscles at the front of the thigh. These are the primary muscles used when performing exercises such as squats, leg press, lunge and leg extension.

2. Hamstrings – these are the main muscles at the back of the thigh. These are the primary muscles used when performing leg curls.

3. Gluteals – these are the muscles that make up the buttocks.

4. Hip flexors – these are the small muscles at the front of the pelvis that allow you to raise your legs to the front.

5. Calves – these are the two muscles found in the lower leg.

For beginners these muscles should be exercised as follows:

1. Leg press – 1 set of 10-15 reps. This is a useful exercise for the quads but it also works the hamstrings and glutes to a lesser degree.

2. Leg extension – 3 sets of 10-15 reps. This is a useful exercise for adding definition to the quads.

3. Hamstring curl – 3 sets of 10-15 reps. This exercise isolates the hamstrings.

4. Standing calf raise – 3 sets of 10-15 reps. This exercise works the gastrocnemius muscle.

5. Seated calf raise – 3 sets of 10-15 reps. This exercise works the soleus muscle underneath the gastrocnemius muscle.

As with all exercises you need to take care in scheduling specific body parts. To begin with you should incorporate your lower body exercises into a program similar to the one suggested below:

Day 1: Biceps, Back, Abs

Day 2: Hamstrings, Shoulders, Abs

Day 3: Quads, Forearms, Calves

Day 4: Triceps, Chest, Abs

For the first couple of weeks complete one set but then add one set each week to a maximum of three. At the end of three months you will be ready to move on to more intensive intermediate level exercises.
