Program Guide
nSuns 5/3/1 LP is a high-volume linear progression program created by Reddit user nSuns that combines the periodization principles of Jim Wendler's 5/3/1 with the aggressive weekly progression of a linear program. The result is one of the most effective intermediate strength programs available, known for producing rapid increases in the squat, bench press, deadlift, and overhead press. The program has gained a massive following online due to the consistent and often dramatic strength gains users report.
The core of nSuns is its unique set and rep scheme for the main lifts. Rather than the three working sets of traditional 5/3/1, nSuns prescribes eight to nine working sets per main lift, with percentages that ramp up to a top AMRAP set and then back down. This high volume on the primary movements provides an enormous amount of practice with heavy weights, which drives both neural and muscular adaptations. The AMRAP set is the key to the program: your performance on this set determines whether you increase your training max the following week.
The five-day version, which is the most popular, dedicates each day to a primary lift paired with a secondary lift. Monday pairs bench press with overhead press. Tuesday pairs squat with sumo deadlift. Thursday pairs bench with close-grip bench. Friday pairs deadlift with front squat. Wednesday is reserved for accessories only or can be a rest day depending on the variant you choose. This pairing system ensures that each of the four main lifts receives direct heavy work once per week and secondary lighter work once per week.
Progression is weekly and based on AMRAP performance. If you hit three or more reps on your AMRAP set, you increase your training max by 5 to 10 pounds for lower body lifts and 2.5 to 5 pounds for upper body lifts. If you hit only two reps, you keep the same weight. If you get one or zero reps, you decrease your training max. This auto-regulation ensures that progression matches your actual recovery and adaptation rate rather than following an arbitrary schedule.
The assistance work in nSuns is where you address individual weaknesses and add hypertrophy volume. After the main and secondary lifts, you perform three to five accessory exercises targeting the muscle groups trained that day. Common choices include rows, lat pulldowns, curls, triceps work, lateral raises, and ab exercises. The assistance work is not rigidly prescribed, which gives you freedom to customize the program to your needs. Most lifters perform three to four sets of 8 to 15 reps per accessory exercise.
The volume of this program is significant. A single session of main work alone consists of 17 total sets between the primary and secondary lifts. Adding four to five accessories brings the total to around 30 sets per session. This volume is what makes nSuns so effective but also what makes it demanding. Sessions typically last 75 to 90 minutes, and the cumulative fatigue from five sessions per week requires strong recovery habits. Nutrition must be on point with adequate calories and at least 0.8 grams of protein per pound of body weight. Sleep should be at least seven hours per night, and stress management matters more on this program than on lower-volume alternatives.
The 12-week duration allows for substantial strength gains. It is common for intermediate lifters to add 30 to 50 pounds to their squat and deadlift and 15 to 30 pounds to their bench press over this period. Some lifters run nSuns for longer, but building in a deload week every four to six weeks is advisable to prevent accumulated fatigue from compromising performance.
One common criticism of nSuns is that it can be taxing on the joints, particularly the shoulders and lower back, due to the high volume of heavy pressing and deadlifting. To mitigate this, ensure your warm-up is thorough, include adequate pulling volume in your accessories to balance the pressing, and do not hesitate to take an extra rest day if your body is telling you it needs one. The program is a tool, and the best tool is one used intelligently.
nSuns is not a beginner program. You should have at least six months to a year of consistent training experience and be proficient in all four main lifts before starting. You should also be comfortable working at high intensities and managing fatigue across a training week. If you meet these prerequisites and want to push your strength to the next level, nSuns delivers.
