When it comes to building muscle, your body only knows or cares about the tension, fatigue and damage an exercise is generating… not the type of equipment you were using when performing that exercise. It really couldn’t give the slightest crap about that. For this reason, ALL types of exercises and ALL types of equipment are capable of stimulating muscle growth.
Why less volume for the smaller muscle groups, you ask? Partially because they are smaller, but mostly because they get a ton of indirect volume while training the bigger muscle groups (e.g. your biceps get hit pretty hard while training back, triceps get hit pretty hard while training chest and shoulders, shoulders get hit pretty hard while training chest, etc.).
Just because your hip flexor region feels sore doesn’t necessarily mean the muscles there are tight — in fact, they might need strengthening. This is where that sports science debate we mentioned earlier comes into play. It’s important to identify whether you’re tight or if the muscles are weak. Again, the Thomas Test will help you identify if you’re maybe stretching something that actually needs strengthening.
The spine has a natural curvature in it in order to function correctly. With their attachment on the spine and pelvis, tight hip flexors can cause an unnatural curve of the spine called hyperlordosis. Hyperlordosis affects the way forces are distributed in the spine and can cause pain and soreness in the lower back. Other common problems that are associated with hyperlordosis are weak abdominal muscles, weak hamstrings, tight low back muscles, as well as tight hip flexors. This can lead to hip flexor and groin strains and hamstring strains…..an all around mess!
As you've probably heard from any muscle-bound behemoth you've ever encountered, protein is the key to building muscle. Just because the shake-pounding meathead has become a trope, however, doesn't mean they're wrong; protein really is the fuel your muscles need to grow. That's real capital-S Science, not just bro-science manufactured by supplements companies.
Glutes are king as far as the hierarchy of your muscles is concerned. “For athletic performance, overall lower body power, strength, speed, and everyday optimum function, honing strength in and activating your glutes should be a top priority in all exercise programs,” says Robert Reames, C.S.C.S., Gold’s Gym Fitness Institute and Pear Training Intelligence System’s weight control coach.
Do Belgian squats (or "single leg squats") with a dumbbell. Hold out in front of your chest a dumbbell using both hands. Standing in front of a bench, lift your right leg back so that it's parallel to the floor and resting comfortably on the bench. Bend into a squat using the left leg, so that the right knee almost hits the floor. Lift and repeat 3 x 8. Repeat using opposite leg.
Reaching failure matters because tension matters. Failure is when the muscle cannot generate anymore force. Which means one applied (worked out) enough tension through the muscle to just want to give up. And guess what? Carrying groceries can do this for some. Why? We are all at different strength levels. So don’t worry about other people and what they can or cannot lift. I say this because FAILURE can be achieved with either light weights or heavy weights.
There are nutrients within these fat sources which decrease inflammation, improve mental function, improve eyesight, and give you healthier skin, hair, and nails. When I'm crushing the iron in the gym each day, my goal is to be strong and big, but also healthy and mobile. To get that way, I eat all of these generously on a regular basis, and I also take omega-3 supplements daily, in the form of fish oil or krill oil.
