When to Lift Heavy and When to Lift Low
March 13, 2014
When to Lift Heavy and When to Lift Low In the popular world of our fitness culture, the indiscriminate use of free weights, machines and spring-loaded resistance is synonymous with strength. More weight is commonly perceived as better and therefore must be leading to better results. However, given the fact that a lot of people injure themselves due to the improper use of weight / resistance, the most popular question that I encounter is when to use more weight and when to use less. The answer lies in what muscles and what percentage of them a person wants to recruit and if there is dysfunction or injury in any segments of the body. Therefore we must look at the concept of ‘stability’ and how combining the right formula will promote optimal strength and mind-body control. Allow yourself to look at how most people workout. Men for example typically focus so much on upper body muscles mass that the lower part of their bodies do not match the top half…big biceps and skinny calves. Woman are big into wanting to ‘spot train’ certain areas…wanting to avoid every other area and target only one. It simply does not work. You can’t have one without the other and if there is no stability at the deepest level within the body then lifting too heavy a weight or trying to tone just a certain area will eventually lead to dysfunction at another segment of the body and the result is imbalance of strength and stability. Lets take a look at some of the main muscle groups in our body; stabilizer, global, and postural muscles. Local Stabilizer muscles are very deep – their main function is to ‘stabilize’ against the load and force that is being presented. However, they are recruited not by force, but rather by the neurons in our brain – In other words, you have to tell them to work and do what they are supposed to do. When we anticipate a movement, we turn them on without even knowing it…think of how your body automatically reacts if you were told to catch something. You would stabilize your body more if you were anticipating catching a weighted object as opposed to a feather! When there is injury or dysfunction in the body – these deep muscles usually turn off – that’s when the bigger ones, the global muscles, take over and do a job they are not intended to do. The Global muscles are the ones that make us move. They are closer to the surface of the body are the ones responsible for moving our joints, such as when performing a bicep curl and taking on the force of a heavier load. However, in the presence of injury the deep (local stabilizer) muscles typically turn off so now we are asking the bigger ones to do more than one job – to stabilize as well as mobilize. So the point is this – the local ones need to turn on first and you need to tell them to turn on – this is where the mind body principle comes in to play. Then your bigger muscles can take on as much load as you are capable of. If your bones are able to move the muscles with the right awareness and timing then the force you put upon it is really dependant on your strength and control and what you set out to achieve. Using lighter weights works more of your postural muscles – the ones that hold us up and make us aware of our form. Heavier weights increase muscles mass and give us more concentric muscular control. So the rule is this – make sure your local stability is doing what it’s supposed to do first – give you good form and control while increasing the force, or the demands you put upon it. If your form and control is good with using a lighter weight then you can start to add heavier. Think smart and you will move smart! Smart Movement translates to a balance in muscle groups and in how to stabilize them before you move them. In turn it produces movement that appears to be effortless and graceful no matter what load you put upon it. Bringing awareness to what you are doing, why you are doing it, and what you are working to achieve will always make the movements look better; body and mind working together as one
