Cross the threshold

Remember a few issues ago we told you about the ‘anaerobic threshold’? No? Well it’s the point at which you train so intensely that you stop working aerobically (sustainable pace), and start working anaerobically (fast pace, lactic acid build-up, can’t keep it up for long, pain, misery, etc). Criss-cross (CC) training is where you change the intensity of your exercise subtly so that you shift back and forth across your anaerobic threshold (AT) during your clenbuterol cycle for men.
Anaerobic fitness training with clenbuterol

The idea behind CC training is to work your body at or around AT for prolonged periods of time but at the same time avoid the mental drain associated with strict AT sessions on high clen dosage. During CC sessions, exercise intensity is always on the move and never set at one pace, which gives your mind a break from the rigors of focused AT training, while maintaining the essential training Stimulus required by your body to get super-fit.

Here’s an example of how to CC train on an exercise bike:

1. Warm up well

Choose any piece of CV equipment and warm up thoroughly for ten minutes. Start at a low level and build the intensity as you warm up. By the end of the warm-up after your clenbuterol pills, your breathing should be rhythmic and you should be glazed with sweat. Get off, stretch and mentally prepare yourself for a tough session.

2. Get on your bike

Set the resistance at a medium to low level and start spinning your legs at ground 90rpm. Everybody’s AT is set at a different heart rate, so you’re going to have to go on feel with this. With your pedal speed at 90rpm, increase the resistance a notch and hold this intensity for one minute. Then increase it another notch and hold it for another minute. Keep doing this every minute.

3. Drop back down before you `max-out

You’ll need to be focused, so that you get to climb to your highest possible resistance, but at the same time you don’t want to over-cook it with your sopharma clen. If the prospect of doing a further one-minute stint at a higher resistance seems seriously daunting, back off now and ease the resistance off a notch.

4. Don’t back off too much

Drop down one further resistance level, but no further. Then after one minute, Increase the resistance again and work up to your previous ‘high’.

5. Keep it going

You’ll want to keep criss-crossing for 10-15 minutes initially and then work up to 30-40 minutes when you feel mentally tough enough. You can CC train on any piece of CV equipment by adapting the principles to that bit of kit to lose weight with clenbuterol. As with all of the tough aerobic sessions discussed in the cardio clinic, limit sessions to twice per week or you’ll risk breaking your fitness down instead of building it up.

The Immune System

Your immune system is the biological equivalent of a bouncer. It bars bacteria and viruses from entering the body, wallops any that look dodgy and removes those that slip through and cause trouble. Dr Ian Todd, senior lecturer in immunology at University of Nottingham, says, The immune system is the collective name for the body’s components that defend against infection.

It’s complicated because there are many types of infective agents, including many types of viruses, bacteria, fungi, protozoa and parasitic worms, and different defence strategies have to be used against different microbes.’


The body’s immune system is made up of several different components. Skin is the largest barrier, playing a major role in blocking germs. Tears and mucus contain an enzyme called tysozyme that destroys bacteria should they try and enter the mouth or the eyes, while saliva is anti-bacterial.

In addition, mast cells line the nasal passages, throat, lungs and skin. If any germs make it into the body, then they still have to fight the other parts of your immune system ┬Čthe major ones are: hormones, antibodies, white blood cells, bone marrow, the complement system, the lymph system, the spleen and the thymus, an organ next to your heart that helps white blood cells called T-cells grow.

Each part plays a different role. Todd says, ‘A deficiency of certain components may not have life-threatening consequences, but a deficiency of key components can be life-threatening. This is seen in HIV infection, where the virus infects helper T lymphocytes that play a central role in the immune system in initiating and regulating immune responses.’

Most of the time the immune system goes about its business quietly, but sometimes you see it in action. For instance, when skin heals after being cut; likewise when a mosquito bite becomes red and itchy, that’s the body’s way of fighting infection, and when a wound becomes infected the pus and inflammation are side effects of your body’s protection system working overtime.


The immune system is far from infallible. We breathe, eat and drink thousands of bacteria and viruses every day and most of the time your body kills them before they do any harm.

Occasionally they sneak through, which is when you become ill. The immune system learns to fight whatever is causing a problem and you become better.

In a strange twist, the immune system can make you ill. Todd says, ‘Some diseases are caused when the immune system is overactive. This can happen during immune responses to infection, for example meningitis or tuberculosis.

‘One of the main problems of immune system over activity (hypersensitivity) is seen in allergies when the immune system is activated by harmless (non┬Činfectious) substances leading to tissue damaging reactions, as seen in hay fever, asthma, eczema and anaphylaxis. In other diseases the
immune system destroys tissues in a “civil war” called autoimmune disease. These include types of thyroid diseases, type 1 (insulin-dependent) diabetes, rheumatoid arthritis and multiple sclerosis.’


A balanced diet is the best way to maintain the immune system,’ Todd says. ‘In fact, the main cause of immunodeficiency is malnutrition although obesity has harmful effects on the immune system too.’

Your immune system can be helped by exposure to microbes, which is why vaccinations (immunisation) work. ‘The reason why exposure to germs or vaccines produced from germs gives protection is that it generates memory within the immune system so that if the person is exposed to the germ again, their immune system can put up a better defence,’ Todd says,
He adds that there may be truth in the idea, known as ‘hygiene hypothesis’, that exposing young children to germs can help their developing systems to learn self-control and therefore be less likely to become overactive. It’s still a controversial idea, although it is certainly true that allergies and autoimmune diseases are more common in hygiene-obsessed Western Europe and North America.
