Why You Should Squat Heavy

I recently watched a DVD on overhead throwing athletes and rehabilitation that featured Mike Reinold and Eric Cressey. Reinold is a well-known physical therapist (owns and operates Champion PT in Massachusetts). Cressey is a widely respected and highly educated strength and conditioning coach. Anyways, on the DVD Cressey spoke about the injury threshold of a muscle or human body. The idea was that a strong muscle is less likely to get injured in comparison to a weak muscle (Well that’s common sense).

Now let’s apply that same knowledge to the squat. Imagine in your head, two friends that are relatively the same body weight, height and age. Friend X could perform a 1RM (repetition-maximum) of 135 pounds. Friend Y could perform a 1RM of 405 pounds. The logical (and correct) thought would be that Friend Y would be less prone to injuries.

Friend Y could do yard work, work a full time desk job, and partake in a weekend kickball game without pain. When Friend X tried to do the same activities, he ran into trouble. I’m going to ruin the surprise for you and tell you that X eventually developed back pain an overuse knee pain. Why did this happen???

Muscles have a certain capacity to perform work. The larger the capacity, the more reserve they have. Let’s use the biceps as an example. Let’s say your best bicep curl is 100 pounds for 1 RM. If your biceps performed 5 pound curls every minute for 8 hours, it could probably hold out and last. However, what would happen if your best bicep curl was only 20 pounds for 1 RM. Your poor biceps are not going to be able to sustain lifting 5 pounds every minute for 8 hours. Eventually you potentially develop tendonitis, DOMS (delayed onset muscle soreness) or even rhabdomyolysis. They may have to amputate the arms because you just killed it too hard with curls (just kidding!).

Now, let’s switch out the biceps for the squat muscles. The squat muscles would include quads, hamstrings, glutes, core etc. If your squat muscles can sustain and lift a heavier 1RM, your body will certainly be more resilient to injuries. Standing up and sitting down would be an easier task if you had strong squat muscles. Navigating stairs or going on long walks/hikes wouldn’t be such an issue with strong legs/core.

The point I’m trying to make and get across is that you should lift heavy! Don’t be afraid to challenge yourself to a 1RM or 3RM. Make sure you have an experienced coach or trainer assess your technique before attempting a personal record. Staying in your comfort zone and performing body weight squats for high reps is not a bad thing. However, you are selling yourself short by not seeing what your body is capable of. If you’re young and able, I challenge you to find that personal record and try to continuously improve your strength. It will be mentally and physically good for you.

There have been numerous studies and articles written on how muscle loss and weakness is positively correlated with death and a shorter life span (1-7). The squat, when performed correctly and with good programming, will improve core strength, increase muscle mass/power/strength, increase your resiliency to injuries and improve your life expectancy.

When I was in physical therapy school, we learned that walking speed and weakness was directly correlated with how long an elderly person had left to live (8). Exercise is the best medicine. Think of heavy squats as a necessary nutrient in your life. Take your squat vitamins and don’t be afraid to drop it like its hot SQUAT!

Hope you enjoyed this fun post,
