Different Ways To Resistance Train
We all have personal reasons why we workout:
gain strength
increase balance
correct muscle imbalances
heal an injury
boost mood
reduce aches and pains
lose weight
All of these benefits are gained from something called hypertrophy. Hypertrophy means increasing lean muscle.
Why is muscle mass lean? Muscles fibres are much thinner and denser than body fat per pound. The more lean muscle you have, the higher your metabolism, meaning you require more calories to function day to day (helps you lose weight). Plus, more lean muscle means more balance, more strength, and more support for joints.
Lately I have seen a plethora of posts on social media incorrectly pushing that you must lift heavy weights to increase muscle. I am here to tell you that it’s not the only way!
Years ago, I used to lift heavy weights. It wasn’t my favourite way to work out, but I did it because all my fellow trainers did. My joints were often sore from the heavy loads, and eventually I received two acute injuries: once in 2002 I sprained a ligament in my low back (left sacroiliac joint) and in 2018 I strained my rotator cuff (left supraspinatus tear). After the tear, I did what I do best and researched (my old journalism degree coming in handy). I found a high quality study demonstrating there are various successful resistance training methods for hypertrophy. And while researching for this article, I found a bunch more (linked below).
To keep things simple there are three ways to resistance train to increase lean muscle:
high load/low reps - lifting super heavy where you can only lift 3-5 repetitions each set
moderate load/moderate reps - lifting enough resistance where you can only reach 10-12 reps each set
low load/high reps - lifting a slightly lighter resistance where you can perform 15-25 reps each set
All have been scientifically proven to increase lean muscle equally. The secret formula? With all three scenarios you need to challenge your muscles to reach near fatigue (without breaking good form). So even with lighter weights, you need to pick a resistance that is challenging for your muscles.
It takes skill and expertise to develop a series of exercises and rep ranges to deliver the correct dosage for hypertrophy. This is one of my favourite elements of my career. That is why I never “wing” the sessions I teach. I purposely plan every single workout I instruct, with specific goals in mind.
Here at PLS we often perform moderate weight/moderate reps, as well as, lower weight/higher reps, and rarely ever lift super heavy. Why? Studies show you are able to stay more consistent when exercises feel good and when you are not consistently sidelined by injuries from placing unnecessary stress on the joints. Why lift heavy, when you don’t have to?
There are people who love to power lift, while there are others who enjoy the burn of barre. That’s why the results of these studies are so amazing, empowering us to choose which resistance method fits us personally.
Next time someone tells you Pilates Equipment or Barre or not lifting “heavy” is ineffective, proudly show them the studies in the resource section of this post and tell them your trainer intelligently builds your body strong, all the while preventing injuries and feeling good. It’s a win win :)
