Most fitness apps are built so you never fail. Primus is built so you don't fail when it matters. This is a 26-week Special Forces training program modeled on the real demands of BUD/S, SWCC, and military selection — two sessions a day, six days a week, combining running, swimming, and strength work into one uncompromising progression. WHAT'S INSIDE Two daily workouts blending running, swimming, and strength Endurance programming that drops your mile times and builds real pool confidence Bodyweight strength: push-ups, pull-ups, sit-ups, and core work at selection volume Flexible lifting blocks that adapt to whatever equipment you have Scalable progressions — adjust to your level without ever losing intensity WHO IT'S FOR Future candidates for Navy SEAL, SWCC, and other special warfare pipelines Athletes who want military-style training with a real structure behind it Anyone done with casual fitness and ready to build discipline, grit, and peak output A WARNING This is not a casual fitness app. Primus demands serious commitment, time, and effort. If you're not ready for an intensive program, start smaller and come back when you are. MINIMUM STANDARDS TO BEGIN Run 2 miles Swim 500 yards 3 pull-ups, 10 push-ups, 15 sit-ups Below that? Prepare first. The program will still be here. 26 weeks from now, you'll either be selection-ready or you'll know exactly why not. Start Week 1 today.

Complete hybrid athlete programming — hybrid, strength, power, engine, tactical. For the weight room, the trail, the start line or selection. 7-day free trial. Built for people with real obligations and no spare time who stay hard anyway. A job. Kids. A business. Forty-five minutes in a garage before anyone else is up. Written by a strength coach and laid out week by week. Not a list of workouts — a plan that goes somewhere, progressing off what you actually logged. THE TRACKS Hybrid — strength and conditioning together, in the order that lets both improve. Barbell work, kettlebells, calories on the bike, running that stays real running. Strength — heavy push, pull and legs. Every muscle group twice a week, loads climbing on percentages, tested at the end. Power — learning to produce force fast. Olympic lifts and derivatives, sprint work, jumps and throws. Engine — running as the point and everything in support of it. Threshold pace, running economy, and the ability to hold pace when it stops being fun. Tactical — built around a report date. Rucking, running, strength and the durability work that keeps you in it. Or build your own and the app writes a program around your goal, your schedule and the equipment you actually have. STARTING FROM BEHIND Coming back after time off, the four-week on-ramp gets you training properly before your real program starts. Submaximal, RPE-based, no max lifts required. When it's done you go straight into day one of the track you picked. STANDARDS AND TESTS Track the numbers that matter and watch them move — squat, bench, deadlift, the mile, the ruck, work capacity. Military standards are in here too: ACFT, PFT, SFAS and RASP preparation for anyone pointed that way. WHAT YOU GET Every session logged — sets, reps, load, time, distance, calories — carried forward into the next one. A weekly debrief that reads your training and tells you what to adjust. Nutrition guidance and recipes built around the training load. Progress photos, PRs and a record book that stays yours. A community in Discord and a founder who answers. Subscription required after the trial. Monthly or annual. Consult a physician before beginning any training program. SOFReady is training preparation and does not represent undisclosed selection standards.
