Pumpkin spice and pull-ups!

Summer may still technically be here until later in the month, but pumpkin-flavored beverages are officially everywhere and that basically means it's fall — or is that just us? Either way, it's no excuse to slack on your summertime fitness regimen! If you haven't exactly been sticking to a routine, there's no better time to get back into it.

To keep you on track, we've rounded up some of the roadblocks that can sabotage a fitness goal we've all had at one point or another: rock-solid abs. Whether that means a visible six-pack or a strong foundation for the rest of the movements you do in the gym, everyone should strive to strengthen these necessary muscles.

A new month also means a new fitness quest, and this time the exercise you'll master is ... pull-ups! Are they hard? Yes. Are they impressive? Also yes. Angela Gargano, our summer cover and repeat American Ninja Warrior competitor, teaches you everything she knows about the simple yet taxing exercise. And trust us, she knows a lot.

And of course, don't neglect nutrition. Whether you need to brush up on your overall knowledge or are looking to follow a plan, we've always got you covered when it comes to eating for your fitness goals.

Stay strong, Oxygen fam!

Some of the most common core-training mistakes go far beyond the actual exercises you’re doing. Therefore, a deeper understanding of what’s going on from a nutrition, genetic and anatomical perspective is crucial to see where you’re falling short on your journey to chiseled abs.

Here, we’ll take you through some common blunders and the mechanisms behind building a concrete core.
