Resistance training is one of the most effective ways to build muscle, develop strength, and protect your long-term health — but it doesn't have to take over your schedule and the rest of your life. In this article, we’ll go through seven evidence-based resistance training ‘hacks’ that can save you time without compromising gains. By using a few of these strategies, you should be able to get your workout sessions down to about 30 minutes.
Most people who want to start weightlifting but tend to avoid it say the same thing: they don’t have enough time. Traditional gym lore tells you you need 90-minute workouts, 6 days a week, with 30-40 sets a session with dozens of exercises, so it’s understandable why many people stay away from it.
That version of training is really reserved for a select few elite athletes, who would probably get the same (or possibly better) results by reducing their training load. They’re probably training for a completely different reason and purpose than you are, so why copy them?
Muscle growth and strength gains are driven by a handful of things: volume (how much you train), effort (how hard you train) and consistency. Each of these can be achieved in a surprisingly short window of time when you do the right things. Here are seven ways to get the most out of training for the least amount of time.

1. Train with the Most Efficient Dose
Estimated Time Saved: 20-30 minutes
Training ‘volume’ is the total number of sets completed per muscle group and probably the primary driver of muscle growth [1]. More volume generally means better gains, but returns start to diminish after a certain point. The evidence seems to suggest this is around 10-12 sets per muscle group. Beyond this point, you tend to accumulate fatigue more than growth. Research also shows that as few as two sets per muscle group are needed to stimulate meaningful growth.
Traditional gym programmes often prescribe 3–6 sets per exercise across 3-5 exercises for the same muscle group, so up to 30 sets total. This is more than most people need, especially for beginners and intermediate lifters. A “minimalist approach” of 2-6 sets per muscle group per week, performed to a high level of effort, produces meaningful results.
In practice: instead of doing 4 sets of three different variations of the same chest exercise, pick 2 exercises and do 2 sets on each.
2. Choose the 'Right' Exercises
Estimated Time Saved: 5-10 minutes
Not all exercises are equal when it comes to ‘time efficiency’. Multi-joint (“compound”) exercises work across two or more joints, engaging several muscle groups simultaneously. This means more muscle is trained per set, so you need to do fewer exercises overall.
Compare a barbell back squat to a leg extension machine. The squat loads your quads, glutes, adductors, lower back, hamstrings, calves and abs simultaneously [2]. Whereas the leg extension only works one muscle group at a time, the quads.
Similarly, select bilateral exercises where both limbs work at the same time (e.g., bench press, barbell row, deadlift) rather than single-leg or single-arm exercises; these take twice as long to do, and there doesn’t seem to be any extra benefits [3].
If you’re really tight on time, pick exercises that don’t take a lot of time to set up or warm up for. Dumbbell, cable and machine-based exercises are just as effective for muscle growth (compared to free-weight barbell exercises) [4]; and you can (generally) get through these types of exercises a bit quicker. However, the best exercise is also one you can perform safely, confidently, and without a long wait for equipment.
3. Cut Your Rest Time — But Smartly
Estimated Time Saved: 5-10 minutes
Rest between sets is not wasted time; you need to rest between sets. Shortening it too aggressively will affect your performance and, in turn, your growth. However, you can also rest for far longer than necessary.
Research suggests 1–3 minutes of rest between sets is optimal for most exercises [5]. Heavier ‘compound’ lifts may benefit from up to 3 minutes. Most people don’t need five.
The most effective way to use rest time is the ‘agonist-antagonist superset’, which pairs of exercises work opposing muscle groups. For example, biceps curls followed immediately by triceps pushdowns, or a bench press followed by a row. Because one muscle group rests while the other works, no formal rest period is needed between them. Research shows that it doesn’t affect your training performance, but saves you a lot of time [6].
If full supersets don't suit your session, you can still use rest productively. Use your rest period to warm up for your next exercise, or adjust your weight or set up the equipment for it. These small tweaks will reduce dead time without interfering with your recovery between sets.
4. Use Time-Saving Set Techniques
Estimated Time Saved: 5-10 minutes
Two training methods let you compress several sets into a shorter timeframe without affecting muscle growth.
Drop sets involve performing a set to near failure, then immediately reducing the load by 10–30% and continuing for another short set. You repeat this for one to five ‘drops’. Research shows drop sets produce similar gains to traditional multi-set training in considerably less time [6]. They work best with dumbbells, cables, or machines — not barbell exercises where changing plates mid-set is slow and disruptive.
Cluster sets (or ‘rest-pause’ sets) break a traditional set into small ‘clusters’ with 10–30 second rest pauses built into the set. Instead of completing 10 reps straight, you might do 4 reps, rest 15 seconds, do 4 more, rest again, and finish with 2. The total reps and load match your standard set, but the brief in-set rest allows each ‘cluster’ to be performed ‘better’ (e.g., better form, technique, higher effort, load, or power). There is research suggesting rest-pause sets may produce slightly better strength (not size) gains than traditional sets [7].
Both techniques can replace one or two traditional sets, cutting the total number of sets and the time required per session.
5. Keep Your Rep Tempo Efficient
Estimated Time Saved: 3-5 minutes
There's a persistent idea that lifting slowly leads to better muscle growth. The evidence doesn't support it. Research shows reps lasting 1–2 seconds produce equivalent growth to 8-second reps [8]. Very slow reps — over 10 seconds — may actually be less effective, not more.
A sensible tempo of around 1–2 seconds on the lift and 2–3 seconds on the lower is fine. But there's no need to artificially slow things down beyond that. The lowering phase (the ‘eccentric’) is where a lot of growth stimulus comes from, so control it throughout the rep — don't just drop the weight. That is gravity doing the work, and a missed opportunity for gains. The lifting phase can be performed with intent and reasonable speed.
6. Warm Up Specifically, Not Generally
Estimated Time Saved: 5-10 minutes
A 10–15 minute cardio warm-up before lifting is not necessary for most people. A specific warm-up is faster and more targeted: one or two lighter sets of the same exercise you're about to perform. This rehearses the movement, ‘activates’ the relevant muscles, and prepares the joints you'll actually be loading.
Static stretching before lifting is also not recommended. Short stretching bouts have minimal effect on lifting performance, and longer sessions (30+ seconds per muscle) can temporarily reduce your strength. Save any stretching for after your session (at home) — or skip it entirely if mobility is not a limitation for you.
A practical approach: do one set at roughly 50% of your working weight, then one set at around 80%, then go into your full working sets. This takes 3–5 minutes and prepares you better than a cardio-based general warm-up.
7. Arrive With a Plan
Estimated Time Saved: 5-15 minutes
Much of the time lost in the gym isn't spent lifting — it's spent deciding what to do next, waiting for equipment, or trying to remember what weight you used last time. A clear plan eliminates all of this.
Before each session, write down: the exercises you'll do, in what order, how many sets and reps, and what weight you'll be using (based on your previous session). A simple training log — paper or an app — takes under five minutes to prepare and saves far more than that in in-gym indecision. Tracking your previous weights also ensures you're progressing over time, which is critical for continued growth [9].
Factor in the gym environment. Most gyms are busiest in the early morning (6–8 am) and early evening (5–7 pm). If you can train mid-morning, lunchtime, or later in the evening, equipment waits will be shorter. If peak times are unavoidable, have a backup exercise for every movement — if the squat rack is taken, use the leg press; if the cable machine is occupied, grab dumbbells. Flexibility doesn't hurt your session if you've planned for it.
Key Takeaways
None of these strategies is radical. But when used together, they can save you time, possibly cutting your session in half without compromising gains. This means better ROI (for your time).
The biggest savings often come from the unglamorous stuff, but it has to be said. Avoid doing unnecessary volume, spend your rest time productively, and plan and record what you’re doing. The lifting itself isn't what takes long — it's everything around it. So optimise it, and don’t make it into a barrier.
