Your legs carry you around all day, every day, and they also deserve some attention in the gym. Beefier, stronger legs are also more proportionate to the desirable muscular V-taper look, which is a goal for some men. You know what they say about skipping leg day. Personally, after a good leg workout, I can definitely feel my strength enhancing in my quads. After some of my more intense workouts or if it’s been a while, I might get that jelly leg feeling and soreness the next day.

The quadriceps

The quadriceps are the large muscles at the front of your upper thighs. Stronger quads help everything from walking and climbing to knee health. One interesting study found that individuals with osteoarthritis who had stronger quadriceps also experienced less knee pain and better overall physical function.

I came across data on the average size of a military man’s quadriceps. We look at the military as a group of people who have to maintain a certain degree of physical fitness to do their duties. That being said, I was interested to see the average quad size. Are military men staying committed to leg day and pumping those quads?

This measurement of the entire thigh includes body fat and encompasses more than just muscle mass, so it shouldn’t be the sole indicator of your leg day progress and your quad size alone. Even so, it’s still a good indicator overall and could motivate you for your next leg day.

The 2012 Anthropometric Survey of United States Army Personnel involved 4,082 male military members. The data showed the average circumference measurement of the male thigh is:

62.51 cm or 24.61 inches

Tips to grow those quads

Here are some top tips to help you grow those quads:

It’s best to mix up your workout routine with a range of different quad-focused exercises, including compound movements like back squats and Bulgarian split squats, as well as isolation moves like leg extensions.
Don’t skip your rest days.
Try mixing up your rep ranges and incorporating progressive overload, where you increase the weight, reps, or sets over time as you get stronger and fine-tune your technique.

I ran in 90-degree heat in these new Saucony shoes — here’s how they held up

Saucony Ride 18 summer

Summer running can bring joy and pain. Joy in the form of sunrise (or sunset) miles, sharing a run with friends, or appreciating nature. Pain arises when the temps creep past 90 degrees, and a leisurely pace feels like a sprint through the desert.

Saucony released the Ride 18 Summer to accommodate those highs and lows, with materials and style that match the season. I tested the shoe during a heat wave in Virginia’s Shenandoah Valley, and it surprised me in some ways, and left me wanting in others. Here’s my take.

Here’s why fitness festivals are booming and building a sense of community

Fitness festivals bring the atmosphere of a music festival to a community workout event.

Music festivals have been popular for many years as a place for melodies, meetings, and more. As a musician myself, in my experience, most music festivals have a welcoming and uplifting atmosphere where people listen, sing, dance, and celebrate a shared love for music. Music is a universal language. In the lyrics and words of Bob Marley, music is a language we all understand. Recently, we’ve seen the increasing popularity of the fitness festival, which puts a different spin on a classic event.

What’s the average size of male biceps? Here are the muscle metrics

This interesting data reveals the average measurements for male biceps.

Some want to grow bigger biceps for the aesthetics and to sculpt a more muscular physique, and others just want to boost strength and fitness. When we think about a strong male upper body or a powerlifter, we envision those bulging biceps under boulder shoulders and next to defined pecs. Interestingly, the size of the bicep muscles could be an indicator of long-term health, and working those biceps is typically included in most resistance training and strength training programs.

Staying dedicated to your arm workouts, upper body days, and bicep exercises pays off in the long run, and research reveals that resistance training does build muscle. Of course, not everyone has arms like Arnold Schwarzenegger's or those of leading bodybuilders in their prime, but when I heard about the data on the average bicep size, I was certainly interested. Let’s check it out.
