When most people craft a resistance‑training routine, the emphasis inevitably lands on the big, showy lifts — squats, deadlifts, bench presses, and rows. These movements are undeniably effective for building strength, muscle mass, and overall performance, and they should form the backbone of any solid program. But there’s a catch: they don’t hit every muscle equally well.
By focusing almost exclusively on the major compound lifts, many lifters unknowingly leave out substantial muscle groups capable of meaningful growth and performance benefits. These “forgotten” areas not only contribute to aesthetics but also play crucial roles in joint stability, movement quality, and injury prevention.
Below, we break down three commonly neglected movement patterns and the muscles they train — plus practical ways to bring them into your routine.
Why Neglected Muscles Matter
The theory behind typical resistance training is straightforward: if you progressively overload a muscle repeatedly, it tends to grow. That’s hypertrophy, and it’s a major driver of strength gains over time. Yet the muscles actively worked during standard multi‑joint lifts don’t cover all of the body’s movers and stabilizers.
This is where the “law of diminishing returns” becomes useful. Beyond a certain point, piling on more sets for already‑well‑trained muscles yields only incremental benefits. Meanwhile, muscles that rarely receive direct stimulus may remain underdeveloped — even in seasoned lifters.
Adding a small amount of targeted work for these areas — think just a couple of sets a few times a week — can significantly boost total muscle mass and functional strength without greatly increasing training time.
1. Scapular Protraction: Awakening the Serratus Anterior
When you reach forward — pushing open a heavy door, throwing a punch, or finishing a push‑up — your shoulder blades move forward along your rib cage. That motion is called scapular protraction, and it’s powered mainly by the serratus anterior and pectoralis minor.
Most programs don’t include movements that explicitly train this action, yet the serratus anterior alone is nearly as large as the lats — a muscle group most lifters treat as a priority.
Strengthening this often‑neglected muscle can improve shoulder health and performance, support better upper‑body mechanics, and help prevent issues like shoulder instability or winged scapula, where the shoulder blade sticks out awkwardly from the back.
How to train it:
- Push‑Up Plus: At the top of a standard push‑up, continue pushing your shoulders forward without bending your elbows — this extra movement directly engages the serratus.
- Band or Cable Protraction: Attach a resistance band or cable at chest height and push forward, focusing on extending the shoulder blades.
- Wall or Elevated Variations: If full push‑up strength is still a challenge, begin with easier versions against a wall or bench.
2. Hip Flexion: Targeting the Often Overlooked Hip Movers
Many lifters assume that squats and deadlifts cover the lower body thoroughly. While those movements are powerful and foundational, they don’t emphasize hip flexion — the action of lifting the thigh forward.
Hip flexion isn’t just about aesthetics; the muscles that perform it — including the iliacus, psoas major, rectus femoris, and others — play a key role in walking, running, sprinting, and posture. Collectively, these muscles form a complex with a combined volume comparable to some of the body’s largest movers, making them too significant to ignore.
How to train it:
- Cable or Band Hip Flexion: Stand or sit and pull the thigh toward the chest against resistance.
- Hanging Leg Raises: These not only work hip flexors but also challenge core stability.
- Machine Hip Flexion Movements: If your gym has hip flexion attachments, even low weight can stimulate growth.
3. Hip Abduction: Strength Through the Side
Hip abduction — moving the leg out to the side — is another movement easily skipped in conventional programs. This action works the gluteus medius, gluteus minimus, and tensor fasciae latae, muscles that collectively rival the size of the gluteus maximus.
These muscles are essential for stabilizing the pelvis during walking, running, and single‑leg movements. They also support athletic performance and protect against knee and lower back issues caused by poor mechanics — a point echoed by many fitness experts emphasizing overlooked stabilizers like glutes and core for injury prevention.
How to train it:
- Side‑Lying Leg Raises: Simple but effective, especially with a resistance band.
- Cable Hip Abduction: Stand next to a cable machine and lift the leg outward against resistance.
- Band Walks: Lateral band walks keep the hips engaged through multiple steps.
Getting Started: A Simple Plan
You don’t need drastic changes to benefit from these often‑skipped movements. Many lifters see noticeable improvements by adding just two sets of each movement twice a week.
Here’s a sample micro‑routine to complement your existing training:
- Scapular Protraction: 2–3 sets of Push‑Up Plus
- Hip Flexion: 2–3 sets of Cable or Band Hip Flexion
- Hip Abduction: 2–3 sets of Side‑Lying Raises or Band Walks
Consistency — even at low volume — usually pays off quickly when a muscle is previously under‑stimulated.
Final Thought
Neglected muscles aren’t a sign your current program is “wrong.” Rather, they are opportunities — low‑hanging gains you might be missing. Incorporating a few targeted movements can elevate strength, balance muscular development, and promote long‑term joint health.
So next time you plan your workouts, think beyond the big lifts. Your shoulders, hips, and stability muscles deserve a place on the program too — and the payoff could be bigger than you expect.
