Muscles are stupid
 
Your muscles don’t know and don’t care what kind of equipment is used to exercise them. They simply respond to exercise stresses placed upon them in terms of intensity throughout a movement range. In simple terms, intensity means how hard the exercise is to perform, especially as measured against a muscle’s maximum ability.
 
There are several ways of understanding and expressing what “maximum ability” means. To the casual exerciser, the idea of maximum ability is a self-described perception of difficulty. The standard term for this is Rating of Perceived Exertion (RPE), which asks the exerciser to use a numerical scale to describe the intensity.
 
There are several REP scales in use. The traditional RPE protocol measures intensity on a scale of 6to 20, with 6 meaning a perceived difficulty equating to very, very light and 20 meaning very,very hard. (For an in-depth discussion about RPE, see my blog posting Exercise: Measuring Intensity).
 
Serious, dedicated exercisers and fitness professionals measure strength-exercise intensity in relation to - and as a percentage of - the heaviest load an exerciser can “lift” one time, using proper form, tempo, and moving through the full movement range. This is called the 1 repetition maximum (1RM). If an exerciser can, say, bench press 100 pounds one time, then they would perform their exercise routine using a percentage of their 1RM for their multiple-repetition set. Example: if 100 lbs is your 1RM, than 80 lbs would be 80% of your 1RM, and is a measurable standard for performing a multiple-repetition set. In this regard, less than 70% of 1RM is considered low intensity, 70-80% is moderate intensity, and 80-100% of 1RM is high intensity. Low intensity training is appropriate for developing muscularendurance; moderate intensity is best for developing muscular strength and size; and high intensity develops maximum strength and power.
 
Back to your stupid muscles. Because your stupid muscles don’t know if they are bench-pressing an 80 pound barbell, two 40 pound dumbbells, or an equivalent weight on a bench press machine, the load factor is basically the same. (Yes, there are some nuanced differences between different kinds of equipment, but they hardly matter in the context of a single exercise session.)
 
Muscles are smart
 
Your muscles quickly figure out the amount of stress placed upon them on a regular basis and adapt by becoming stronger to accommodate those stresses. Indeed, adaptation is the cornerstone of how we survive as a species – whether it’s adapting to a climate, available foods, necessary skills, societal roles, or anything else that allows us to be viable under circumstances that have changed, or that may be different from the circumstances of other people.
 
Because your muscles are smart and adapt (by becoming stronger) to repeated exercise sessions using the same equipment and the same loads, over time they end up working less hard to perform those exercises. This is what is commonly known as reaching a plateau, or stall, and your progress stalls, as well.
 
Outsmarting your muscles
 
There are several strategies for breaking through the dreaded plateau, but all of them involve changing what you’re doing, and none of them involve continuing to do the same thing. Typical changes may include all or some of the following:
 
  • Change the order of exercises. Example: If you’ve doing full-body routines, working your back, chest, and legs in that order, try reversing the order to legs, chest, then back.
 
  • Change the exercises. Yes, you’ll want to continue exercising all the same muscle groups, but try using different exercises. Example: If you’ve been doing leg-presses for your thighs and glutes, try doing dumbbell squats instead. Or, instead of performing leg presses using both legs at the same time (bi-lateral), try reducing the load to 50 percent of the bi-lateral resistance and do your leg presses as a separate set for each leg (unilateral) individually. There are many different exercises that can be used for every muscle group, so there is no need to always do the same exercises, the same way, all the time.
 
  • Change the equipment. This is one of my favorite techniques for breaking through plateaus, as well as avoiding or delaying them altogether. By changing the equipment you not only continue working the same muscle groups, but you will recruit the same muscle fibers in a slightly different way, which will enhance the training effect of your workout and keep your workouts fresh and your progress moving forward.
 
By the way, making the kinds of periodic changes to your workouts as discussed above can done be with home-based workouts, as well as at the gym. If you are doing home-based training, you probably have some basic equipment – perhaps a pair of dumbbells, a stability ball, and a pair of ankle weights. Add an inexpensive set of resistance tubes and you’re well on your way to being able to perform numerous exercises for every muscle group, and at varying intensity levels.
