A barbell complex is a run of barbell lifts done back to back without putting the bar down. Mine is 10 rounds of 2 deadlifts, 2 hang cleans, 2 push presses and 2 front squats, with 2 minutes of rest between rounds. That's 80 reps in about 25 minutes. My caption said to put your bodyweight on the bar, and I used 205. For most people that's too heavy. The push press sets the weight, and a bodyweight push press is roughly the one-rep max of a typical lifter. Start with a bar you can push press 9 or 10 times fresh, and add weight only when round 10 stays clean.
I'm 37, about 200 lb, and I hold 8–10% body fat year-round. The same caption says this workout "keeps me shredded." On its own, it doesn't. Both lines get a straight answer below.
What is a barbell complex?
A complex is a series of lifts done back to back, with no rest and without putting the bar down. That's close to word for word how an NSCA TSAC Report by Tim Lentine and Jay Dawes defines it. They credit Istvan Javorek with making complexes popular, first as conditioning programs for Olympic weightlifters.
Their usual range is 3 to 6 exercises, 3 to 6 reps of each, 1 to 6 sets, and 3 to 5 minutes of rest between rounds. Mine breaks that range in three places: 2 reps instead of 3 to 6, 10 rounds instead of 1 to 6, and 2 minutes of rest instead of 3 to 5. Short rounds are what make 10 of them on 2-minute rests possible.
The tradeoff is load. Matt Foreman at Catalyst Athletics puts the general rule in two lines: "Long complexes = lighter weights. Short complexes = heavier weights." Eight reps a round is short, so the bar can be heavier than in a complex of 6 reps per lift. Heavier still doesn't mean bodyweight for most people.
What is the exact workout?
Ten rounds of 2 deadlifts, 2 hang cleans, 2 push presses and 2 front squats, with 2 minutes of rest. Here it is as I posted it (the reel is here):
10 rounds
- 2 deadlifts
- 2 hang cleans
- 2 push presses
- 2 front squats
- Rest 2 minutes
Do all 8 reps without letting go of the bar. The deadlifts take it from the floor to your hips. The cleans take it from the hang to your shoulders. The presses take it overhead and back, and the squats keep it in the front rack. Every lift uses the same overhand grip. The NSCA report recommends one grip for every lift in a barbell complex, so you never change hand position or put the bar down mid-round.
The reel's on-screen headline says 25 minutes, and the arithmetic agrees. Ten rounds means 9 rests, and 9 × 2 minutes is 18 minutes of rest. If a round of 8 reps takes about 35 seconds, the work adds up to about 6 minutes. That's about 24 minutes in total.
At 205 lb, 80 reps move 205 × 80 = 16,400 lb on the bar. Twenty of those reps are push presses, and that's the number to plan around.
How heavy should a barbell complex be?
Lighter than bodyweight for most people. The push press sets the weight, not the deadlift.
The NSCA report calls this the "load-limiting" exercise: the weakest lift in the complex decides the weight for all of them. It also says you can't use as much weight in a complex as in normal sets, because the fatigue stacks up from one lift to the next.
In this complex the press is the weak link for almost everyone. On Strength Level, the average man's one-rep max is 180 lb on the push press, 189 lb on the hang clean, 231 lb on the front squat and 340 lb on the deadlift. At 200 lb bodyweight, the site puts an "intermediate" push press at 195 lb, and intermediate means stronger than 50% of lifters. So for about half of the 200-lb men in that data, a 200-lb bar is more than they can push press once. The caption asks for 20 push presses at that weight. One limit on that data: lifters submit their own numbers, and people who log their lifts probably skew stronger than average.
Here's a rule of thumb, not a study finding. Start with a bar you can push press 9 or 10 times fresh. That comes from BarBend's guide to barbell complexes, which says to pick a weight you can "comfortably do nine or ten reps" with on the lightest lift. Strength Level's rep table puts 10 reps at about 75% of a one-rep max. For an average 180-lb push press, that's 180 × 0.75 = 135 lb: a 45-lb bar and a 45-lb plate on each side.
BarBend's rule is for sets of 5 to 6 trips through the complex, which it calls "high reps for a complex." Each round here is one trip with 2 reps per lift, so Foreman's "short complexes = heavier" rule gives you room to go up. Earn it one session at a time:
- If your presses in round 10 grind or turn into a slow press-out, the bar was too heavy. Go lighter next time.
- If round 10 looks like round 1, add the smallest plates you have next time.
- Change only the load. Keep the reps and the rest the same, so you know what made the difference.
Bodyweight is my number. It's a fine goal and a bad starting point. If the press is what holds your bar down, here's how to increase your overhead press.
Is a barbell complex good for fat loss?
It helps, but your deficit does the fat loss. The calorie burn is modest, and the math shows how modest.
The 2024 Adult Compendium of Physical Activities has no entry for a barbell complex. The two closest are vigorous free-weight lifting at 6.0 METs (code 02050) and vigorous circuit training with minimal rest at 7.5 METs (code 02040). One MET is about 1 kcal per kg per hour (Herrmann et al., 2024). Subtract 1 MET for what you'd burn sitting anyway. For a 200-lb (90.7-kg) lifter over 25 minutes:
- (6.0 − 1) × 90.7 × 25/60 ≈ 190 net kcal
- (7.5 − 1) × 90.7 × 25/60 ≈ 245 net kcal
Treat 245 as the high end. Eighteen of those 25 minutes are rest, and code 02040 assumes minimal rest.
Now put that next to walking. At 200 lb, walking burns about 40 net calories per 1,000 steps (bodyweight ÷ 5). So the whole complex equals about 4,800 to 6,100 steps. The 10,000 steps a day I teach burn about 350 to 400 net calories at that weight, every day. And a standard 500-calorie daily deficit is 3,500 a week. One complex a week covers 190 to 245 of that, about 5 to 7%.
That's why "keeps me shredded" is too generous. What holds me at 8–10% year-round is the boring part: I weigh in every morning, log every macro, and lift 4 days a week. A complex is one good session inside that. It isn't the reason. The full case, with the formats that fit a busy week, is in conditioning workouts for fat loss.
How is it different from the bear complex?
The bear complex is five lifts: power clean, front squat, push press, back squat, and a behind-the-neck push press, one rep of each, per Jamie Bain at Rugby Renegade.
Mine starts with a deadlift from the floor, uses a hang clean instead of a power clean, and drops the back squat and the behind-the-neck press. The bar stays in front of you the whole round, on one grip, and every lift gets 2 reps instead of 1.
The HYROX-style workout is a different thing again. That one is a ladder for time, and the clock is the score. This complex is rest-paced. The 2-minute rests are part of the prescription, and how clean round 10 looks is the score.
How often should you do a barbell complex?
Once a week is enough, on top of your lifting, not instead of it. Foreman writes that there's "no definitive guideline" on frequency, "but I think once a week is plenty."
Per the NSCA report, the main purpose of complexes is muscular endurance and exercise capacity, and "more traditional strength programs may be better suited" to building strength and power. So the complex goes next to your lifting days. It doesn't replace one.
When round 10 stays clean, progress one lever at a time. The NSCA lists four: shorter rest, more load, more reps per lift, or more lifts. Pick one, write it down, and run it again next week. That's the No-Guess Loop on a barbell: track what you did, review how round 10 looked, adjust one thing, and build on it.
