🥴Ooff… after taking a week off to get packed up and move home last weekend, I can tell you that stepping foot back in the gym this has been a painful one lol 🤪

‼️Let’s talk about that!
Delayed onset muscle soreness (DOMS) is a well-documented physiological response that occurs following resistance exercise, particularly after unaccustomed or intense activities, especially those involving eccentric muscle contractions!

👉🏼For seasoned lifters—which applies to many of you reading this, the severity of DOMS can increase significantly after even a short period of detraining 🥲

😮‍💨On return to lifting, there are a number of cellular responses including the activation of satellite cells, the release of inflammatory cytokines, and the recruitment of immune cells to the affected areas. This inflammatory process contributes to the sensation of soreness, stiffness, and reduced range of motion.

☝🏼Additionally, the psychological factors associated with returning to training can often contribute to greater DOMS, as lifters often push themselves “harder” than normal after taking time off, amplifying the risk of muscle damage and soreness. 🙋🏼‍♀️This definitely applied to me this week😅

⚠️ If soreness persists beyond 72 hours or significantly impacts performance in subsequent training sessions, it may be necessary to reduce training intensity or volume.

When I’ve taken extended periods off training, I like to implement a progressive overload strategy that gradually increases load and incorporates adequate recovery protocols!

Who else has taken some time off, and what was your experience getting back into lifting!? Comment below👇🏽

🔥 Many Roads to Muscle 💪🏽 3-5 reps vs. 20-25 reps in Advanced Lifters
(🎥 Watch the Full Study Breakdown on my YT channel)

🧠 Background:
A brand-new 2025 study by Cummings et and colleagues explored whether performing 3–5 reps @ 90-95% 1RM or 20–25 reps @ 40-60% 1RM is better for muscle growth and strength in trained lifters.

Previous research by the like of Schoenfeld et al (2015) have shown that both can work if you train to failure, but this new paper tested the extremes of loading — something not often done in experienced athletes.

Methods:
🔹 14 trained men & women (2+ yrs experience)
🔹 Each leg trained differently — one heavy, one light
🔹 9-week program, 2 sessions/week (leg press + leg extension)
🔹 All sets to failure, standardized post-workout protein

📊 Results:
Both training styles led to similar increases in muscle thickness (~7–8%, or 0.1–0.2 cm).
💪🏽 Strength gains were mixed — the leg press improved equally, while the leg extension favored heavier loads.
At the cellular level, satellite cells increased in Type I fibers (slow-twitch) in both conditions, while Type II fibers and myonuclear number remained unchanged.

🧠 Discussion:
Even among trained lifters, both light and heavy training built comparable muscle. The key difference? Heavier loads offered a slight edge for strength, particularly in single-joint exercises. The modest hypertrophy likely reflects the short duration and low total weekly volume — not necessarily the load itself.

Takeaways:
✅ You can build muscle with any load if you train close to failure
✅ Heavy loads are best for maximizing strength
✅ Lighter loads are a great option for joint issues, recovery phases, or personal preference
➡️ Bottom line: There’s more than one road to muscle growth. Choose the one that fits your body and lifestyle — consistency beats load perfection.

💥 How Close to Failure Should You Train?
🎥 Watch the full study breakdown on YT🍿 (Link in bio)

A brand-new 2025 study by Martikainen et al. asked a question most lifters wonder:

👉 Do you need to train to absolute failure to maximize gains?

🔍 Methods:
39 resistance-trained adults completed a 10-week program using one of two approaches:

Group 1: Trained with ~1 rep in reserve (RIR 1) every set.

Group 2: Started 4 reps from failure (RIR 4) and progressively got closer each week until RIR 1.

Both groups trained 4 days/week (upper-lower split) with supervised check-ins, online tracking, and video reviews. Researchers measured muscle size (ultrasound), 1RM strength, and RIR accuracy before and after training.

📊 Results:
✅ Both groups increased strength and muscle size similarly:

Squat 1RM ↑ ~9–10%

Bench 1RM ↑ ~7–10%

Vastus lateralis size ↑ ~5–6%

Triceps thickness ↑ ~2–6%

💪 The progressive RIR (1–4) group reported lower effort (avg RPE 6.9 vs 7.7) but achieved the same results — and actually became better at judging their RIR by the end of the study.

💭 Discussion:
Both constant and progressive RIR strategies were equally effective for trained lifters. The main difference? The progressive approach may feel easier and lead to more consistent progress across individuals.

That said, with a small sample, short duration & with both groups training with a similar proximity to failure, its reasonable to say this study may never have been positioned to reveal a meaningful difference in the first place.

🏁 Conclusion:
After 10 weeks, training close to failure (RIR 1–4) produced similar muscle and strength gains as training to near failure every set — but with less perceived effort and improved effort awareness.

So if you’re wondering whether every set has to be all-out... the answer might be: not always. 😉

💡 Takeaway: Gradually pushing closer to failure could help you manage fatigue, improve RIR accuracy, and still grow just as effectively.
