The goal is to make the muscle work hard enough that it adapts and gets stronger. I've seen more confusion about this term than almost any other in fitness. If you're new, start with two sessions a week, pick five basic movements, and leave the fancy programming for later. This page covers the core exercises and how to progress. Resistance exercise training (RET) has emerged as a cornerstone of modern exercise science, with a growing body of clinical evidence supporting its use beyond mere muscle building. In patients with heart failure, combined endurance and resistance training improves functional outcomes and offers an evidence-based foundation for clinical management [1]. Meanwhile, neuromechanical studies show that the adaptations to RET depend on exercise selection, multi-joint versus single-joint movements produce distinct changes in muscle activation and mechanics [2]. Even in cancer survivorship, a 10-week hybrid RET program proved feasible, acceptable, and safe, suggesting that resistance training can be adapted to fragile populations [3]. RET also carries significant metabolic and mental-health benefits. In females, resistance training appears to favorably alter the metabolism of visceral white adipose tissue, a key driver of cardiometabolic disease [4]. For young women with depressive symptoms, a randomized controlled trial found RET significantly reduced depressive symptoms compared to a low-intensity sham control [5]. Given that midlife women face increased hypertension risk with cerebrovascular implications [6], and chronic anxiety is linked to irregular sleep and vascular dysfunction [7], integrating RET into clinical and preventive care may offer a practical, scalable intervention for both physical and mental health. Together, this evidence positions resistance exercise training as a versatile therapeutic tool, not just for strength, but for systemic health. ## Pick a rep range and match the load Reps don't exist without weight. For strength, keep 3-6 reps heavy. For muscle growth, 6-15 with moderate load. For endurance, 15 or more. Pick one goal and stick with it. You can't optimize for all three at once. Change rep ranges every 8-12 weeks if you need a change, not every session. ## How do you know when to add weight? When you hit the top of your rep range on all sets with a rep or two left in the tank, add weight. Upper body jumps of 2.5-5 kg work. Lower body can handle 5-10. If you can't hit the bottom of the range next session, you added too much. Back off. ## Set your weekly split by movement patterns Train each muscle group twice a week, not once. Use full-body sessions or an upper-lower split. Put compound movements first: squat, hinge, press, row. Then accessories. A simple template: Monday full-body, Wednesday full-body, Friday full-body. That's enough for most people. If you can only manage two days, do a full-body split each time. ## Log your sets and review weekly Write down the exercise, load, and reps after each set. A simple note app works. Look for patterns: which lifts stall, which jump forward. If you're not adding weight or reps over three weeks, change something. A notebook is fine, but Dorsi auto-logs your Apple Watch lifts if you want zero friction. ## FAQ ### What is an example of a resistance training exercise? The back squat. Load a barbell on your traps, drop your hips until your thighs are at least parallel, then drive up. It hits quads, glutes, adductors, and your core has to work hard to keep your spine neutral. If a barbell isn't an option, a goblet squat with a dumbbell or kettlebell is a fine substitute. Rows, presses, deadlifts, lunges all count too. ### Is 20 minutes of resistance training a day enough? Depends what you mean by enough. Twenty minutes a day, five days a week, gives you 100 minutes of quality work. That can absolutely build muscle if you're doing compound lifts, taking sets close to failure, and adding weight over time. What it won't do is cover a lazy program. If you're just doing 20 minutes of light cables, that's not enough. Choose hard exercises and actually progress them. ### What is the best resistance training exercise? The trap-bar deadlift is the one I'd pick for almost anyone. It loads your quads, hamstrings, glutes, grip, and upper back in one movement, and you can lift heavy without putting your lower back in a risky position. It's easier to teach than a barbell deadlift, and the range of motion suits most people. If you have a decent trap bar, that's your best single exercise. ### What is the best resistance training for seniors? The best program is the one that keeps you independent. That means squats and deadlifts with a manageable load, carries, and pressing, not just machine curls. Start with bodyweight or light dumbbells, get the movement pattern clean, and add load slowly. For most seniors I'd rather see trap-bar deadlifts and goblet squats than leg extension machines. If you can't get up off the floor, strength training hasn't done its job.
