How does Leptin contribute to an increase in bodyfat

Personal Training Clifton

The relationship between Leptin and weight management.

We consume an average of 1 million calories per year. What is amazing is we have a 99.6% accuracy balancing energy in (food) and energy out (exercise, living). The bad news is the more we train the more we eat. After 2 years 70% to 95% of people studied return to their starting weight.

 We use a fat regulating system involving the hormone Leptin. Leptin is released by fat cells and has been shown to decrease apatite. So.. the more fat we have the less we want to eat? unfortunately its not so simple. It looks like Leptin insensitivity has a greater effect on weight gain. Research is limited around this topic but it looks like genes, lifestyle factors and diet could effect the bodies sensitivity to leptin. Our bodies could be fooled into gaining body fat to increase leptin levels.

 Some studies I looked at suggested a link between refined sugars, artificial sugars and fructose (fruit sugars) with a increase in Leptin insensitivity and therefore possible weight gain. Its looking like our genes have a greater play in deciding who has a weight battle and who can have a six pack and eat pies.

 The bottom line is..at this point in time your genes are mapped out, how you choose to deal with them is up to you.Personally I love been fit and fairly healthy. So concentrate on your health; exercise regularly, eat healthy and enjoy life.


Remember one pint is equal to 40mins of brisk walking so space your pubs apart. ;-)

Time to get off the couch

Time to get off the couch. To receive benefits to your health from exercise the recommend weekly activity is 75mins vigorous exercise (Hiit, spin, boxing, Running etc) or 150mins moderate exercise (walking) per week. Research has found that if you exercise more then the recommended amounts the health benefits won't increase proportionally to the amount of exercise. In other words the curve begins to flatten out. This doesn't mean you shouldn't workout more then recommend. We like to train for other reasons like it's fun or we enjoy the challenge. What is scary is in the UK only 6% of males and 3% of females reach this weekly target. The age of the sloth is well and truly here. Research has also found inactivity has the same effect as smoking 20 cigarettes per day on your health. One study found. A fit obese person has 1/2 chance of dying in the next decade then a healthy weight category unfit person. We seem to be obsessed with weight loss when in reality we should be focusing on activity first. Two high intensity classes a week is all you need or just over a 20mins of walking each day. Will help improve your quality of life and help save the NHS. 'You can do it'

Functional Training 101

Personal Training Clifton

Personal Training Clifton

( I wrote this article for a New Zealand fitness mag in 2002 long before I had heard about training systems like crossfit. I missed that boat)

The Advantages of Doing Functional Compound Sets

We are more often looking towards the gym to help give them that edge during sports. There is also a greater desire to achieve the lean athletic look of a sportsperson, without a large increase in muscle mass as seen in bodybuilding athletes. If you want to look like an athlete then it helps to train like one. This article explains how using one technique called ‘Compound sets’ has benefits over traditional weight training, especially when the desired goal is functional performance. You might have heard of compound exercises this is where more than one joint is involved in a single movement (i.e., bench press or squat). A compound set is simply when two or more exercises are involved in a single set.

A large number of traditional weight training exercises originate from a bodybuilding background, which focuses on growth and symmetry of individual muscles or body parts. With this style of training, isolation of joints and muscle groups (i.e., bicep curl or hamstring curl) will occur. If your goal in the gym is for functional athletic performance or weight loss there are three main drawbacks with traditional weight training.

Training the nervous system is highly specific. Isolating body parts as seen in many traditional weight-training exercises will adapt the nervous system to be more efficient at isolated movement. If you train the nervous system to isolate individual muscle groups it will decrease it’s ability to coordinate muscle groups into complex movements such as jumping or throwing a ball. Using compound sets will train the nervous system to coordinate between multiple muscle groups and to achieve a greater number of complex movement patterns. This closely resembles the athletic demands placed on our coordination during sport.

Traditional weight training split programmes causes a short-term muscle imbalance within the body. Fatiguing one muscle group without fatiguing the opposing muscle group creates this muscle imbalance. Research has found the knee is more susceptible to injury if there is an imbalance between quadriceps and hamstring strength, e.g. if you train quadriceps on one day and then hamstrings another day. A well-designed compound set will work the body as a whole and is less likely to cause the body these short-term muscle imbalances.

Boxing personal Training clifton
A large number of sports require an intermittent maximal effort, which places great demands on the anaerobic system. Sports such as netball, tennis, squash and many other sports played in New Zealand require short bursts of sprinting with small rest periods in-between. The greater number of muscles being used at once means a greater amount of energy is required. Heavy load compound sets tend to be more demanding on the anaerobic system because of the larger number of muscles required to complete the exercise. When weight loss is the goal, compound sets can burn more calories for the same amount of time spent on a set. Traditional weight training exercises tend to use a smaller number of muscles during each exercise and therefore burn fewer calories.

The Training Programme

Compound sets should not be used if you have very little or no weight training experience. A six-week conditioning programme designed by a qualified instructor should be completed before introducing compound sets to your workouts. Before using compound sets, practice the individual exercises first. A range of tempos can be used during the sets. It is advised to start with slow tempos until the individual feels fully competent with the complex movements.

Follow this programme for no more than four weeks or add these compound sets to an existing programme.

Weight training 2 - 3 times per week. One day on, one day off. 2-3 days per week do cardio and core-stability (Abdominal and lower back).

Example: 4 Week programme

Sets Reps Load Rest
Week 1 2 15 Light 90
Week 2 3 12 Medium 60
Week 3 3 12 Medium 60
Week 4 4 10 Heavy 45

Compound Sets:

1. Burpee-out, Press up (Knees or Full), Burpee-in, Power-clean, Push press (Using Dumbbells)

Starting Position
Place dumbbells shoulder width apart with the handles parallel to each other.

Burpee-out.
Grip dumbbells shoulder width apart, keep back and neck in neutral position. Keep abdominals strong, burpee out to press up position

Press up.
Start press up at full position or move to knees. Keep back and neck in neutral position throughout entire press up.

Burpee-in.
If press-ups were preformed on knees return to full position. Burpee in toward barbell and adjust to starting power clean position.

Power-clean.
Feet should be between hip and shoulder width apart, toes forward and slightly outward. Standing with back rigid and flat or slightly arched. Simultaneously fully extend the lower extremity joints and quickly shrug shoulders. Pull arms as high as possible. After the lower body has fully extended and the bar reached near maximal height, pull the body under the bar by rotating arms and hands. The bar should be caught across the shoulders.


Push-press
Bend the knees slightly as if starting a squat then explosively push the dumbbells up using your calves, legs and arms. Finishing in a shoulder press position. Keep your abdominals strong throughout the movement and be careful not to hyperextend the lower back.

Finishing
While maintaining a flat back slowly flex the hips and knees and lower the dumbbells to the starting position.


2. Hang Clean, Front squat, Push Press

Starting Position
Feet should be between hip and shoulder width apart, toes forward and slightly outward. Standing with back rigid and flat or slightly arched. Bar resting slightly above knees

Hang Clean
Simultaneously fully extend the lower extremity joints and quickly shrug shoulders. Pull arms as high as possible. After the lower body has fully extended and the bar reached near maximal height, pull the body under the bar by rotating arms and hands. The bar should be caught across the shoulders.

Front Squat
Feet should be between hip and shoulder width apart, toes forward and slightly outward. Keep elbows high, eyes on the horizon and the chest up. Move with hips first then knees. Squat as if sitting into a chair, keeping the abdominals strong. Stop decent if the heels start to rise or the pelvis tilts backward. Stop when the thighs are parallel to floor.

Push press
Start push press halfway through up phase of the squat. Explosively push up the dumbbells up using calves, legs and arms. Finishing in a shoulder press position. Keep the abdominals strong throughout the movement and be careful not to hyperextend the lower back.

Finishing
While maintaining a flat back slowly flex the hips and knees and lower the dumbbells to the starting Hang clean position.



3. Backwards Lunge with barbell, High knee.


Start
Stand with barbell in finished shoulder press position. Hand position should be wider than the shoulders. Arms should be straight, do not lock out elbows (this exercise should be started with the weakest side first and the same amount of reps preformed on both sides).

Backwards Lunge
Perform a backwards lunge while keeping barbell in fixed position. Keep feet parallel and hips facing forward throughout the entire movement. Keep eyes on the horizon and the chest up throughout the exercise.

High Knee
Return to starting position. Then, using the same leg used in the backwards lunge, lift the knee as high as possible while maintaining a neutral back position.

Finishing
Once the knee has reached maximum height the cycle should then repeat by starting a backwards lunge again.
