Reps in Reserve: How Hard Your Sets Actually Need to Be
Most men in the gym fall into one of two camps. One leaves every set feeling pleasantly warm — the weight moved, nothing was really hard. The other grinds every set into the ground and wonders why their shoulders ache and their progress stalled. Both are missing the same idea: effort is a dial, and the useful range is narrower than you think.
Reps in Reserve (RIR) is simply how many more good reps you could have done when you stopped. 0 RIR is failure. 2 RIR means you had two clean reps left.
What the research shows: Studies comparing training to failure with stopping short find that muscle growth is broadly similar as long as sets end within roughly 0–3 reps of failure. Strength gains follow a similar pattern. What changes is the cost: going to failure every time generates much more fatigue, slows recovery between sessions, and — for men over 40 — puts extra stress on joints and tendons at exactly the point where form tends to break down.
The problem for most men isn't going too hard, though. It's badly underestimating how much they had left. When researchers ask lifters to predict their reps to failure and then test it, people commonly stop 4–6 reps short of what they could actually do on higher-rep sets. That's a set that feels productive and does very little.
How to use it:
Big compound lifts (squats, deadlifts, presses): 2–3 RIR. These are the lifts where a failed rep is risky, and the fatigue is highest.
Machines and isolation work (curls, lateral raises, leg extensions): 0–2 RIR. Low risk, low fatigue — you can push these closer.
Last set of an exercise: a reasonable place to take it to 1 RIR or technical failure and learn where your real limit is.
Deload weeks and warm-ups: 4+ RIR, on purpose.
Hard enough to matter, short enough to recover. That's the window where men over 40 make steady progress for years.
Supplement Spotlight: Whey Protein Isolate — The Simplest Way to Hit Your Protein Target
Whey isn't a performance enhancer in the exotic sense. It's food — milk protein, filtered and dried. But as a way to close the gap between the protein you eat and the protein you need, very little beats it.
Here's what it does: Whey is a complete protein that digests quickly and is naturally rich in leucine, the amino acid that switches on muscle protein synthesis. A 25–30 gram serving delivers around 2.5–3 grams of leucine, which matters more after 40, when muscle needs a bigger per-meal signal to respond. The isolate form is filtered further than concentrate, so it's typically 90%+ protein by weight and very low in lactose — often tolerable for men who find regular dairy uncomfortable. The research shows that whey supports muscle gains when combined with resistance training, mainly by helping you reach your daily protein total. It isn't better than an equal amount of protein from food.
How to take it: 25–40 grams per serving, whenever it fills a gap — breakfast is often the best candidate. Aim for around 0.7–1.0 grams of protein per pound of bodyweight per day from all sources. Timing around your workout is flexible.
Worth knowing: anyone with a milk allergy should avoid it. Men with kidney disease should check their protein target with their doctor. Because supplements aren't tightly regulated, choose a product that's third-party tested (e.g., NSF Certified for Sport).
We recommend whey isolate as the most practical protein backup there is — a tool for hitting your number, not a replacement for real meals.
FROM RYAN’S DESK
The easy path rarely creates a strong man. Challenge yourself. Lift heavier. Push harder. Make the better food choice. Get up when you want to stay in bed. Every time you choose the harder option, you prove to yourself that you're capable of more. Strength isn't just built in the gym. It's built every time you refuse to take the easy way out.
Myth or Real: "Every set should go to failure."
Myth. Going to failure isn't dangerous on its own, but making it the default is one of the most common ways men over 40 stall.
Failure sets produce a lot of fatigue for very little extra stimulus. Take three sets of squats to failure and your third set is often slower and uglier than it needed to be — and you'll feel it for days. The research suggests you get most of the growth benefit by stopping 1–3 reps short.
Where failure does earn a spot: the last set of a safe exercise — a machine, a cable, a curl — once in a while, to calibrate your sense of effort. Where it doesn't: heavy barbell squats, deadlifts, and bench presses without a spotter, where the last rep is also the most likely to go wrong.
Train hard. Just don't confuse "hard" with "as hard as possible, every set."
Question from Our Readers: "How do I know how many reps I had left?"
Honestly — at first, you don't. It's a skill, and most men are poor judges until they practice.
Two ways to calibrate. First, test it safely. On a machine or dumbbell exercise, do your planned set, note how many you think you had left, then keep going to failure. The gap between your guess and reality is your calibration error. Most men discover it's bigger than they expected.
Second, watch bar speed. When reps slow down noticeably despite full effort, you're usually 2–3 reps from failure. When a rep grinds and nearly stalls, you're at 0–1.
Log your RIR next to your weights for a few weeks. Your guesses will tighten up fast, and your training will get more productive without adding a single set.
Our Picks: Supps We Actually Use
Some of our coach’s favorite supplements:
Creatine (Travel Packs) - $36
Add this to your water in the morning or in your post-workout shake. Creatine is one of the few supplements that has a mountain of data proving its benefits. Don’t miss out on it!
A great way to hit your protein goals. Don’t rely on a protein powder alone, but add it as a post-workout shake or midday shake to increase your protein intake and hit your protein goals. Remember, high protein equals higher muscle and higher satiety.
Replenishes essential electrolytes. Use this if you sweat a lot, do intermittent fasting, or go on long-distance walks, hikes, or runs.

Fit Trivia: Which actress — who trained for three hours a day, six days a week with a former Israeli commando to transform her physique — famously knocked out a set of pull-ups in a psychiatric hospital cell in 1991's Terminator 2: Judgment Day?
Answer: Linda Hamilton! Her portrayal of Sarah Connor became one of the most influential images of female strength in film — and the pull-up scene is still a go-to reference for what disciplined training can do.
