6 Resistance Training Rules You Should Break Now

The world of resistance training is full of loud, conflicting advice. Do you train to failure? Is six days a week mandatory? This noise often leads to frustration, plateau, or injury. What if the most common “rules” holding you back aren’t rules at all, but outdated myths?

True progress comes not from following the loudest voice, but from understanding the underlying principles of adaptation and recovery. Drawing on a deep-dive conversation between This article challenges six entrenched training dogmas with science and practical experience. The goal is to help you train smarter, sustain progress longer, and build a resilient body for life.

1. The “More is More” Myth: You Can Get Stronger by Training Less

Direct Answer: Yes. For most people, training a muscle group twice per week is the optimal balance of stimulus and recovery, yielding better long-term results than frequent, grinding sessions.

Explanation & Evidence:
The belief that more gym time equals more gains is flawed due to the law of diminishing returns. The initial high-quality work provides the majority of the growth stimulus; adding excessive volume or frequency offers minimal extra benefit while dramatically increasing recovery demands and injury risk.

“You get so much of your results from the first work set you do… adding more volume, adding more frequency, it’s not linear.”

Analysis & Application:
Prioritize quality over quantity. For most lifters, a well-structured program of 2-3 full-body or upper/lower split sessions per week is sufficient. Focus on making those sessions count with progressive overload and excellent form, then prioritize recovery. More is not better; better is better.

2. Rethinking Progress: The Unstoppable PR is a Dead End

Direct Answer: Absolutely. Expecting to add weight or reps every single workout (linear progression) is unsustainable and leads to guaranteed burnout. A “sawtooth” pattern of cycling your focus is the key to lifelong progress.

Explanation & Evidence:
The human body cannot adapt in a perfectly straight line. Insisting on perpetual personal records (PRs) forces you into a corner of compromised form, overuse injuries, and psychological frustration. A smarter approach, championed by coaches like Louie Simmons, involves cycling your focus between different movement patterns over weeks or months.

Analysis & Application:
Adopt a phase-based approach. Dedicate a 4-6 week block to prioritizing your squat and bench press, for example. In the next block, shift focus to deadlifts and weighted pull-ups, maintaining but not aggressively pushing the previous lifts. This “sawtooth” pattern allows for continuous adaptation without systemic breakdown.

3. Stimulate, Don’t Annihilate: Frequency Trumps Total Destruction

Direct Answer: Correct. The old-school “destroy a muscle once a week” body-part split is inferior to more frequent, sub-maximal stimulation for most natural trainees. The goal is to maximize your Maximum Recoverable Volume (MRV) over time.

Explanation & Evidence:
Pre-steroid era bodybuilders often used full-body routines three times a week. The modern obsession with extreme soreness as a success metric is counterproductive. If an exercise (like walking lunges to failure) leaves you unable to train effectively for days, it has negatively impacted your weekly MRV and total growth potential.

Analysis & Application:
Design workouts that leave you able to train again in 2-3 days. For muscle growth, aim for 10-20 challenging sets per muscle group per week, spread across 2-3 sessions. The sensation should be one of fatigue, not debilitating damage. Save all-out failure techniques sparingly.

4. Glute Training is More Than Squats: The Rule of Thirds

Direct Answer: Yes. Squats and deadlifts alone are insufficient for complete glute development. The “Rule of Thirds” prescribes equal focus on vertical, horizontal, and lateral/rotary movements to target all muscle fibers.

Explanation & Evidence:
The gluteus maximus and medius have multiple functions: hip extension, hip abduction, and rotation. Powerlifters strong in squats may lack glute development because the movement doesn’t maximally challenge the muscle in its shortened position. A balanced approach ensures comprehensive development and resilience.

Analysis & Application:
Structure your glute training around three categories:

1. Vertical (Squats, Lunges): Loads the muscle in a stretched position.
2. Horizontal (Hip Thrusts, Bridges): Maximally contracts the muscle; crucial for “the squeeze.”
3. Lateral/Rotary (Band Walks, Cable Abductions): Targets stability muscles like the gluteus medius.
   Including all three ensures balanced development and can improve performance and reduce injury risk in sports and daily life. For a detailed glute-building plan, explore our guide on science-backed glute training.

5. The Surprising Truth About Maintaining Muscle

Direct Answer: True. Maintaining muscle and strength requires a fraction of the work needed to build it. This principle allows for strategic “specialization phases” where you focus on weak points without losing gains elsewhere.

Explanation & Evidence:
Research, such as the Bickel et al. study, demonstrates this clearly. After a build-up phase, subjects maintained nearly all their quad size and strength for months on just 3 sets per week—a 90% reduction in volume. This shows that maintenance is not demanding, freeing up recovery resources.

Analysis & Application:
Use this for strategic specialization. If your shoulders are lagging, launch a 6-8 week phase where you increase shoulder volume and intensity while putting your well-developed legs into maintenance mode (e.g., 3-5 hard sets per week). You can focus energy on a weakness without the fear of losing progress elsewhere.

6. The Yin and Yang of Lifting: Why Numbers and “Feel” Both Matter

Direct Answer: Essential. Relying solely on objective numbers leads to ego-lifting and poor form. Relying solely on subjective “feel” leads to self-deception and stagnation. The synergy between both is where optimal growth happens.

Explanation & Evidence:
Dr. Contreras highlights the trap of the “mind-muscle connection” purist: “your mind plays tricks on you.” A set can feel grueling yet be objectively lighter than last week’s, indicating stagnation. Conversely, chasing numbers alone often sacrifices technique and increases injury risk.

Analysis & Application:
Keep a training log to track objective metrics (weight, reps, sets). Simultaneously, cultivate internal focus on perfect technique and muscular sensation. Let the logbook tell you what to do, and let your mind-muscle connection guide you on how to do it well. They are complementary, not opposing, forces.

FAQ: Your Intelligent Training Questions, Answered

Q: I’m a beginner. Is twice-a-week training really enough?
A: For the first 1-2 years, yes, it is more than enough. Beginners have a remarkable ability to adapt to a novel stimulus. Two full-body, high-quality workouts per week can produce fantastic results. The key is consistent progression within those sessions, not adding more days prematurely.

Q: What’s a simple alternative to linear progression?
A: Use double progression. Pick a weight you can lift for 3 sets of 8-12 reps with good form. Work with that weight until you can achieve 3 sets of 12 reps across all sets. Then increase the weight slightly and work back up from 3 sets of 8. This creates natural, sustainable waves of progress.

Q: How do I find my Maximum Recoverable Volume (MRV)?
A: Start conservatively. If you’re recovering well between sessions, seeing strength gains, and not feeling chronically drained or sore, you’re likely at or below your MRV. If you’re constantly beat up, getting weaker, or getting sick often, you’ve exceeded it. Reduce volume by 20% and rebuild gradually.

Q: Can I apply the “Rule of Thirds” to other muscle groups?
A: Absolutely. The principle of training a muscle through its full range of motion and various functions is universal. For example, train chest with both horizontal presses (bench) and flyes (stretch); train back with both vertical pulls (pull-ups) and horizontal rows. This ensures complete development.

The most intelligent training program isn’t the most extreme one on paper; it’s the sustainable one you can execute consistently for years. By breaking these six common rules, you move from chasing fatigue to pursuing adaptable strength. You shift from fearing muscle loss to strategically directing growth. Ultimately, you build not just a stronger body, but a more resilient and insightful approach to fitness.
