Trim Trolley

October 29, 2007

trim trolleyHere’s a novel idea: Trim Trolley Takes Off The Weight While You Grocery Shop.

I don’t know about you, but the thought of pushing an unnecessarily heavy trolley around the supermarket just sounds like a pain in the butt. I tend to want to get in and out of the supermarket as quickly as possible.

The concept is a good one though – making something we do often burn a bit more energy – kind of like fortifying bread.

If you are interested in losing fat you could just put less crap in the trolley too!

Stretching to prevent soreness

October 27, 2007

yoga stretchEver since I first started learning about exercise I have been told stretching helps prevent muscle soreness (sometimes called delayed onset of muscle soreness – DOMS).

The exact mechanism that this worked never made sense to me, and some researchers recently reviewing a number of studies actually found there to be virtually no benefit (less than 1 point on a 100 point stiffness scale) from stretching before or after exercise.

Of course there are numerous benefits from stretching, such as flexibility, and so unfortunately it is not an excuse to avoid it all together.

Buying running shoes and injuries

October 26, 2007

KayanoWhat should you look for when buying a running shoe?

Many specialised sport shoe stores market themselves on their ability to test your type of foot, and sell you a shoe that best suits your needs. Usually you are categorised along the lines of needing either a ‘stability’ or ‘neutral’ type shoe.

I am often confronted with the latest and greatest gimic in a pair of shoes and wonder on their actual benefit.

Well, a recent study to come out of the British Journal of Sports Medicine found there to be no relationship between price and cushioning. In fact, there may have been a small negative relationship.

Not that this means you can go out and run a marathon in a pair of commando m’s. The price range the authors looked at was 40-75 pounds.

Often the first thing people blame when they get running injuries is their shoes.

If you find you are getting injuries, the first thing you should look at is the age of the shoes. Secondly, the amount of mileage you have been doing (especially relative to how much you are used to). Thirdly, how many shoes you rotate (or if you only have one pair).

If the shoes are relatively new (less than 6 months) yet worn in, you have not increased your mileage recently, AND you have at least a pair of shoes for every 40km you run a week, then maybe, and only maybe your shoes are to blame.

Rugby place kicking

October 25, 2007

McAlisterAs some of us reflect on what may have been in the World Cup, an interesting study came out about kicking technique.

Using detailed recordings of many top level kickers, the researchers found that those kickers who swing their non-kicking arm across their chest on contact with the ball are more successful than those who don’t – as is demonstrated here perfectly in the picture.

It is especially true for kicks over long distances.

I guess now all we got to do is hope in the future the referee awards penalties to give us a chance…

1RM protocol

October 22, 2007

Testing yourself is an important motivator, and sets a benchmark for training.

The most weight you can lift once (but not twice) is what is known as your One Repetition Maximum, or 1RM.

Below I have outlined the protocol for testing your 1RM. I do however strongly recommend you hook up with an experienced trainer that you trust to do these. This is mostly for obvious safety reasons. The other thing you must do is maintain correct lifting form throughout the exercise.

  1. General warm up 10 minutes
  2. Warm up specific to exercise being tested
  3. 10 reps @ 60% estimated max
  4. Rest, dynamic stretch
  5. 5 reps @ 80% estimated max
  6. 3 reps @ 90% estimated max
  7. 1 rep at 100% estimated max
  8. Rest 5 minutes
  9. Repeat 1 rep at estimated max
  10. Rest 5 minutes
  11. Continue in small increments. Must rest and repeat 5 minutes later to be 1RM.

It is important you estimate close to your actual 1RM to avoid fatigue playing too much of a role. After you have done it once you will have a good idea, in the mean time check this out.

If you are a power-lifter or are lifting high absolute loads then this will not be applicable for you.

Incidental exercise

October 22, 2007

24 hour fitnessThis picture reminds me of an important point regarding ‘incremental’ or ‘incidental’ exercise.

Studies have shown us that this type of exercise is JUST AS IMPORTANT as planned exercising in losing weight / maintaining a healthy weight.

A slightly cynical way you could interpret this is: By just doing these incidental things and not doing a planned exercise you will be getting 50% of the benefits!

So what are incidental things? Take a look at the picture – I am sure you have an idea! Take the stairs, not the elevator. Walk to the shops rather than take the car.

Water drinking competitions

Why water drinking competitions are not a good idea

How many sets should you do at the gym?

October 17, 2007

When you go to the gym, how many sets should you do?

I would say of all the people I know and see at the gym the average would be 20-25 total sets. If you are working in the 3*8-15 repetition range (most people I see in the gym) doing this many sets, then you are either superman, lifting too light, or you are doing the wrong exercises.

The first thing to address is the type of exercises you are doing. A program to lose fat or increase muscle should be based around compound exercises. What I mean by compound is large muscle group exercises. Or you can think of it this way: An exercise in which you move a heavy weight a moderately long distance. If you are not doing these types of exercises because you are not good at them then that is not good enough! If you find them hard, then that is because they are!

Think of a squat vs a finger curl. Which one is likely to stimulate your body into burning calories? I will give you a clue: Not the finger curl!

Secondly, consider the load. As I have mentioned before, this should be at least 60% of the maximum load you can lift once. If you don’t know what this is then work it out. I will post a generic protocol on 1RM testing shortly.

It has been suggested by some that 12 is an optimal number of sets to do in the gym. It is of course hugely dependent on the number of repetitions you do. For example if you are doing 1-5 reps then more sets will be ok. However, generally speaking I tend to agree with 12-15 as a starting point. There is also a lot of scope for warm up sets, rehabilitation sets, and ‘aesthetic sets’ in a program which I would not count in this.

Get these two variables right (exercise selection and intensity) and you will be well on the way to a productive workout.

Nothing tastes as good as thin feels

October 12, 2007

Struggling for some motivation with your eating habits?

Here is a new idea from Diet Incentives that I first saw on dietblog.

With slogans like “Nothing tastes as good as thin feels”, “Lose weight, your horse hates you”, and “Put your hands on your head and step away from the pantry” plastered round your home, how can you not get the message!

There is some irony in putting some of these messages on the bottom of a plate though – you may only see them once you have finished the meal.

Contact Sports and getting into fights

October 11, 2007

I have always subscribed to the theory that playing physical contact sports ‘lets out’ aggression that could otherwise be used off the field.

A recent study done in the US has indicated my long held belief to be wrong. Students involved in contact sports that they looked at were more likely to get into fights off the field than those involved in other ‘non-contact’ sports such as baseball.
