If you're a beginner, just about any workout will be intense enough to increase protein synthesis. But if you've been lifting for a while, you'll build the most muscle quickest if you focus on the large muscle groups, like the chest, back, and legs. Add compound lifts like squats, deadlifts, pullups, bent-over rows, bench presses, dips, and military presses to your workout to work them the most efficiently.
The gluteus maximus can be your best friend when it comes to safely performing backbends. Yet overusing this big muscle by clenching your butt as you backbend can lead to irritation and injury in the spine and sacroiliac (SI) joint. In order to mitigate excessive spinal compression in backbends, it’s helpful to use the buttocks and adductors (inner thighs) to support the weight of the pelvis, hips, and spine. Work on the following actions:
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.).
The gluteus maximus arises from the posterior gluteal line of the inner upper ilium, and the rough portion of bone including the crest, immediately above and behind it; from the posterior surface of the lower part of the sacrum and the side of the coccyx; from the aponeurosis of the erector spinae (lumbodorsal fascia), the sacrotuberous ligament, and the fascia covering the gluteus medius. The fibers are directed obliquely downward and lateralward; The muscle has two insertions: Those forming the upper and larger portion of the muscle, together with the superficial fibers of the lower portion, end in a thick tendinous lamina, which passes across the greater trochanter, and inserts into the iliotibial band of the fascia lata; and the deeper fibers of the lower portion of the muscle are inserted into the gluteal tuberosity between the vastus lateralis and adductor magnus. Its action is to extend and to laterally rotate the hip, and also to extend the trunk.
The good news is that there are plenty of good hip stretches out there that you can do to relieve discomfort, decrease tightness, and increase mobility in your hips. Since your hips are involved in so many of the movements you make (both inside and outside of the gym) stretching them is a great way to keep them feeling good and ready to work for you. Add some of the 12 hip stretches Atkins demos below to the end of your workout, or spend 10 minutes each day just doing a few of them, to improve mobility in your hips.
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.
When it comes to building lean muscle, size bodybuilders are king. That’s their ultimate goal. Sure, Crossfit, powerlifting and all the other modalities will build muscle, but that’s not their focus. They want performance and any muscle they build is a side effect. Not so with bodybuilding where muscle size and shape are the priorities. Learning how to build muscle for the sake of building muscle has some benefits to the performance athlete. It allows for ais less injury prone. Its also a fact that bigger muscle contract harder regardless of technique or form, so it’s a good strategy to throw in some bodybuilder muscle building sessions here and there to give yourself stronger muscles to then train for performance. Build the muscle bigger, then train it to perform better.
Note that this recommendation is for total weekly volume, which means it would need to be divided up based on how many times you’re training each muscle group per week. So, for example, someone training everything twice per week would do 30-70 reps for each bigger muscle group in each of those workouts, and 15-35 reps for each smaller muscle group in each of those workouts.
