Two to three sessions per week, spaced 48 hours apart, maximize strength gains for most people. I program my own sessions this way on Dorsi. The longer your muscles stay under tension the more they adapt. This page covers rep ranges, rest times, and how to know when you're ready to add load. Resistance training sessions don't need to drag on. A 2021 study found that just two 30-minute sessions per week increased muscle strength by 28% in eight weeks. The problem isn't finding an hour at the gym, it's starting. Most people I talk to suffer from workout decision fatigue: they overthink sets, reps, and exercises until they skip the session entirely. That's where a structured approach matters. Dorsi helps you plan efficient resistance training sessions tailored to your schedule and fitness level. For a deeper look, check out our guide on how to get a great workout in 20 minutes with zero planning. In the modules ahead, we'll break down effective resistance training programming, form cues, and how to progress without burning out. ## How many resistance sessions per week should you do? For most people, 3 sessions is the sweet spot. Two gives you progress, but it's slow, especially if you're over 40. Four can work, but I'd only recommend it if you're splitting upper/lower. Anything more than that? You're likely overtraining. The data backs this: a 2022 meta-analysis in Sports Medicine showed 3x/week produced significantly more hypertrophy than 2x, but 4x wasn't meaningfully better. ## Pick compound lifts first, then isolate Start every session with a compound: squat, bench, deadlift, or overhead press. Multi-joint moves recruit more muscle, drive more hormone response. After that, accessories like curls or lateral raises fill gaps. Don't reverse the order, you'll fatigue small muscles first and shortchange the big lifts. I've seen too many guys do 45 minutes of biceps before touching a barbell. Stupid. ## Progressive overload: add weight or reps each session You can't just show up and move metal. You need to add something, 2.5 kg to the bar, one extra rep per set, or one more set. If you do the exact same workout for six weeks, you're not training, you're exercising. Pick a scheme: double progression (hit 12 reps on all sets, then up weight) works well. Track it. Dorsi logs your loads automatically so you never guess. ## Take most sets 1-3 reps short of failure Training to absolute failure every set burns you out and bloats recovery costs. Leave a rep or two in the tank for the first 2-3 exercises. Last set of your last exercise? Sure, go to failure. The research from Santanielo et al. (2020) showed similar hypertrophy between groups going to failure and those stopping 2 reps shy, but the failure group had more fatigue. I'd rather you come back next session fresh.
