  • Did you know that the earliest recognition of resistance bands came in 1896 when a Swiss

  • man by the name of Gustav Gossweiler requested a patent for an elastic exercising device?

  • To be used as a “gymnastic apparatusto replace other apparatusesses, Gustav’s

  • invention laid the foundation for other patents to follow up to this day.

  • And yes, these rubbery tubey porta….bly things has become pretty popular over the

  • years.

  • Question is, do they actually build muscle?

  • Let’s get one thing out of the way first.

  • If youre a beginner, absolutely positively you will see results using bands.

  • Beginners, you guys are lucky.

  • Youll pretty much respond to any type of exercise, including band exercises.

  • Let’s also get a few more other things out of the way.

  • Bands are great for people going through physical therapy, rehab, and the elderly, since it’s

  • lower impact, easier to control, for the most part, and something easy to do at home.

  • And yes, bands are extremely portable.

  • You can get all different colors of the rainbow with very different resistances that can do

  • a bunch very different exercise.

  • Awesome!

  • BUT!

  • Now let’s get to the good stuff.

  • Can it give you all of them beautiful gainz?

  • We know the research definitely show a whole bunch of muscle growth and strength benefits

  • when it comes to beginners.

  • But as you get out of the phase athletes callnewbiegains, making sure to use progressive

  • overload and providing proper stimulus to your muscles is mucho importante for growth.

  • So, what does that mean for bands?

  • Well, let’s talk a little bit about the physiology of muscle contraction first.

  • Warning: boring science ahead!

  • Contraction occurs within a sarcomere via the sliding filament theory, where cross bridges

  • are formed by a reaction between the elements of contraction, actin and myosin.

  • The head of a myosin filament attaches to an adjacent actin filament and forms the so-called

  • bridgeand then pulls the sucker towards the center of the sarcomere.

  • The more it pulls, the shorter the muscle fiber becomes.

  • Such as when you go from straight missiles to gun show!

  • Now, based on different lengths of the muscle fiber, the amount of force you can produce

  • changes.

  • At its longest, force production is lowest due to low contact between the contractile

  • elements.

  • In the mid-range, force is the highest with the most contact occurring.

  • And then weak again at its shortest length, where youre fully flexed, due to overlapping.

  • Here, take this funky scenario for example.

  • A guy is pulling a stone towards him attached to a rope.

  • As he creates slack on the rope, another guy decides to join in behind and help, producing

  • more pull power.

  • The more they pull, the more and more people help out, and produce more power!

  • Eventually, they run of rope space and start stepping back.

  • But, little did they know there was another group pulling another stone right behind them.

  • The two groups get in each other’s way, forcing some people out, and force production

  • dwindles.

  • Now, apply this to muscle force production, and youll see a chart like this.

  • Weakest in the beginning, strongest in the middle, and weak again at the end.

  • I’m not sure if that made any sense

  • Anyway!

  • Youre probably wondering, “How the heck does this have anything to do with resistance

  • bands?”

  • Well…I’ll tell you!...

  • After I explain what that means for your traditional dumbbells!

  • Now, if I were to take a weight where I can lift pretty confidently at the middle range

  • of motion, where I’m the strongest, the weight is probably still no good because I

  • can’t lift it for reps at the weakest part of the range.

  • That means I have to go lighter, of course.

  • But now, the weight is too light in the middle and I’m not getting the maximal stimulus

  • I need for growth.

  • And as far the bicep curl, I’m not getting much of a stimulus at the end neither.

  • I know, I know, I said that youre weaker at the end of the movement, too.

  • But in this case, something in biomechanics known as a moment arm, is very short, meaning

  • the line of resistance is very close to the axis, or your joint or elbow in this case.

  • The shorter the moment arm, the less force needed to move an object, thus, in the bicep

  • curl, not a lot of force produced at the end.

  • I probably confused you even more than before, but let’s continue

  • Okay, now let’s FINALLY look at resistance bands.

  • The resistance applied from elastic bands are different from that of traditional weights.

  • Duh!

  • The WAY it is different is that it applies a growing level of resistance the more you

  • pull through the range of motion.

  • That means, at the very start, the amount of tension and resistance is at its lowest,

  • and then at its highest at the end of the movement.

  • That’s good though, in the case of the bicep curl, because that’s what you want!

  • A growing resistance since youre weakest in the beginning, strongest in the middle,

  • and weak but low moment-arm at the end!

  • But, it’s not great for ALL exercises.

  • Take the side raises, for example, where youre super struggling towards the top of the movement

  • because the moment arm is much greater.

  • And some bands, especially loop bands that are stronger, has an extremely wide range

  • of resistance, like this one, where it goes from 50 to 125 pounds of force, almost 3 times

  • as much from start to finish!

  • So, this is a huge disadvantage to resistance bands, along with the fact that youll grow

  • out of the very light bands really quickly and then using the heavier bands will be tough

  • because itll start pulling YOU instead of you pulling it.

  • As far as gains, it looks feasible, but only up to a certain point.

  • Hold on a minute

  • We know weights have a constant load, which can be good but it also means not enough resistance

  • for the middle range of motion to create an optimal stimulus.

  • And we know bands are good because of a continuous load, but is too low in the beginning and

  • too tough at the end.

  • So, why not combine them together?

  • (windows ta-da!)

  • That’s right!

  • Adding bands onto your weights is probably the best way to go to compensate for the differences

  • in muscle force production.

  • That means greater stimuli, greater volume, and greater gains!

  • In fact, the studies back this up, where one even found, as far as strength, subjects improved

  • their one rep maxes twice as much with bands than using weights alone.

  • (results may vary) So, thesmartway to use bands is to

  • simply use them with your exercises now.

  • But, if you do choose to use bands alone, maybe you can use it as a warm-up set before

  • jumping into weights.

  • Some people even find it useful to supplement a workout with band exercises at the end to

  • push volume up a bit more and creating a heavier pump.

  • And you probably even have some awesome ideas to use with your bands.

  • And if you do, share it in the comments!

  • Anyway, I hope this video was more helpful thanconfusing, and if you enjoyed it,

  • As always, thank you for watching!
