In an age when looksmaxxing influencers have greater social reach than board-certified medical professionals, and the conversation about arbitrary self-improvement is increasingly becoming more granular and scientific-feeling (see: the PSL scale<\/a>), it’s getting harder to differentiate between actual health advice and subjective rules made up by literal teenagers.<\/p>\n

Take, for instance the topic<\/a> of back chain vs. front chain dominance, which posits the notion that the muscles along the back of your body deserve more of your attention than the ones on the front, and becoming \u201cback chain dominant\u201d will inherently make you more attractive. The mere suggestion would be swiftly tossed out the window of any physical therapist\u2019s office. Online, meanwhile, it\u2019s striking a chord<\/a>.<\/p>\n

The thing is, there\u2019s actually some value to this idea, or at least part of it. The problem is that social media doesn\u2019t do nuance. To explain, we thought we\u2019d catch up with a few qualified experts, for old time\u2019s sake.<\/p>\n

What does \u2018back chain\u2019 and \u2018front chain\u2019 actually mean?<\/strong><\/p>\n

Technically speaking, nothing. If we\u2019re being scientific, which we should, considering we\u2019re talking about dishing out consequential health advice, let\u2019s at least use the proper terminology. What we\u2019re actually talking about here are the body\u2019s posterior and anterior muscle chains.<\/p>\n

“Your posterior chain is the group of muscles running along the back of your body,\u201d says Katie Cyrana-Hillery, PT, DPT, OCS, CSCS, physical therapist at Evolve Physical Therapy and Performance<\/a>. The posterior chain, or what social media is calling the \u201cback chain,\u201d includes muscles like your calves, hamstrings, glutes<\/a>, lats, traps, and delts, as well as some of your deeper abdominal muscles<\/a>. While these are all individual muscles, \u201cthey work together to power almost everything you do,\u201d Dr. Cyrana-Hillery says. \u201cWalking, running, jumping\u2014even just standing up from a chair.\u201d<\/p>\n

In the same way that your biceps and triceps work in opposition to one another so that your arm can both flex and extend, your posterior chain is complemented by the muscles on the front of your body\u2014including your quads, hip flexors, and pecs<\/a>\u2014which are known collectively as the anterior chain. \u201cEfficient movement depends equally on both chains,\u201d Dr. Cyrana-Hillery says. \u201cWhen one breaks down, movement gets less efficient and your risk of pain and injury goes up.\u201d Essentially, they are two sides of the same coin.<\/p>\n

Is it better to be back-chain or front-chain dominant?<\/strong><\/p>\n

For the average person looking to live a healthy, active, pain-free life, the answer, unequivocally, is neither. \u201cWe don’t really want dominance in one of them,\u201d Dr. Cyrana-Hillery says. \u201cWe want evenness. It’s not about being posterior-chain dominant or anterior-chain dominant. What actually matters is recruiting the right muscles at the right time and getting both chains to work together.\u201d<\/p>\n

The exception (sort of) would be elite athletes, who naturally tend to drift towards posterior or anterior dominance as a result of the inherent mechanics involved in their sport. “Look at the difference between sprinters and marathon runners,\u201d says Zaki Afzal, DPT, physical therapist and owner of Optimize Physical Therapy and Performance<\/a>. \u201cTheir bodies literally couldn’t be more different, because the demands of their sport are completely different.\u201d While both types of athletes in this analogy are technically running, the sprinter is asking far more of their hamstrings, glutes, and adductors, and therefore more likely than the marathoner to fully develop those muscles. \u201cWhen you look at the energy demands during walking, running, and sprinting<\/a>, the faster you go, the more your posterior chain gets involved,\u201d Dr. Afzal says.<\/p>\n

But even elite athletes aren\u2019t aiming for posterior or anterior chain dominance. In fact, a lot of how the pros train is geared towards evening out imbalances in order to avoid injury. “Truthfully, there’s not a case where it’s better to be more dominant in one,\u201d says Dr. Cyrana-Hillery. \u201cEven in running, you want that posterior chain to be strong, because you want it to propel you forward, but if you don’t have stability from your anterior\u2014your core, your quads, your hip flexors\u2014you’re not going to be able to perform.\u201d<\/p>\n
