You're at the gym. You see someone sprinting on a treadmill for sixty seconds, then immediately dropping to the floor for a set of heavy pushups, only to jump back up and start sprinting again. It looks chaotic. It looks like they can't make up their mind. But honestly? That person is likely doing an up and down workout, and they're probably getting twice the results in half the time you are.
We’ve all been taught to "stay in the zone." You know the drill: keep your heart rate at a steady 140 beats per minute for forty-five minutes and call it a day. Boring. Also, potentially less effective than we once thought. The up and down workout—often referred to in clinical settings as "peripheral heart action" (PHA) training or simply vertical-shift circuit training—forces your blood to travel from your lower extremities to your upper extremities in rapid succession. It’s a cardiovascular shell game. Your heart is the dealer, and it’s working overtime to keep up.
The Science of the Up and Down Workout
Most people think cardio is just running. It isn’t. Cardio is literally just your heart working. When you perform a squat, your body shunts blood to your glutes and quads. If you immediately follow that with an overhead press, your heart has to pivot. It says, "Wait, cancel that order for the legs, we need oxygen in the shoulders right now!" This constant shunting of blood creates a massive metabolic demand.
A study published in the Journal of Strength and Conditioning Research actually looked at this. They compared traditional circuit training (where you might do all upper body then all lower body) to PHA-style training. The results? The "up and down" approach led to significantly higher oxygen consumption and a lower perception of effort compared to the sheer exhaustion of localized fatigue. Basically, you’re working harder, but it feels slightly less like death because no single muscle group is being annihilated into total failure.
It’s about the pump. Not the "bro-science" muscle pump, but the actual systemic movement of fluid. By alternating between "up" (upper body) and "down" (lower body) movements, you prevent lactic acid from pooling in one area. You can keep going longer. It’s efficient.
Why Your Local Gym Bro Probably Hates This
Traditional bodybuilders love "split days." Monday is chest. Tuesday is back. To them, the idea of an up and down workout feels like cardio in disguise. And, well, it kind of is. But for the average person who has forty minutes to spare between work and picking up the kids, split days are often a waste of time.
If you do chest on Monday and then miss Tuesday and Wednesday, your back hasn't been touched in a week. With a vertical-shift approach, you’re hitting everything. Every time.

There’s also the "afterburn" effect, or EPOC (Excess Post-exercise Oxygen Consumption). Because you are constantly forcing your heart to redirect blood flow, your internal thermostat stays cranked for hours after you leave the gym. You’re burning calories while sitting on the couch watching Netflix. That doesn't happen nearly as much after a steady-state jog.
Common Misconceptions
- It’s just HIIT. Not quite. High-Intensity Interval Training is about heart rate spikes and recovery. Up and down workouts are about directional blood flow. You can do this at a moderate pace and still see the benefits.
- You can't build muscle. False. While you won't become a competitive powerlifter this way, researchers like Dr. Thomas Delorme—who pioneered progressive resistance exercise—showed that systemic circulation is a massive factor in recovery and hypertrophy.
- It’s too complicated. It’s literally just alternating. Squat, then row. Lunge, then press. It’s simpler than most apps make it out to be.
How to Structure Your First Session
Don't overthink it. Seriously.
Start with a "Down" move. Let’s say, Kettlebell Goblet Squats. Do 12 reps. Your heart starts pumping blood to your massive leg muscles. Now, immediately—and I mean immediately—move to an "Up" move. Lat pulldowns or even just standard pushups. Do 12 reps. Rest for 30 seconds. Repeat this four times.
Then, switch the exercises. Do Lunges (Down) followed by Dumbbell Overhead Press (Up).
The key is the lack of rest between the "Down" and the "Up." If you wait two minutes to talk to someone about their weekend, you’ve lost the effect. The blood has already settled. You want to catch your vascular system off guard.
Real World Results and E-E-A-T
I’ve seen clients who plateaued on the elliptical for years lose five pounds of fat in a month just by switching to this method. Why? Because their bodies were bored. The human body is a survival machine; it wants to be efficient. It gets "good" at running, which means it starts burning fewer calories to do the same task. The up and down workout is fundamentally inefficient for the body to manage, which is exactly why it works for fat loss and conditioning.
Even elite athletes use versions of this. Think about a basketball player. They jump (lower body), then they shoot or block (upper body), then they sprint (lower body). Their life is an up and down workout. If you want "functional" fitness, this is the blueprint.
Potential Risks
Listen to your head. No, really.
Because you are moving blood rapidly from the feet to the head and back, some people get dizzy. It’s called orthostatic hypotension, though usually, it’s just a mild "head rush." If you feel like you’re going to faint, sit down. Don't be a hero. Your veins have valves that help push blood up, but they aren't magic. Give your body a week or two to adapt to the pressure changes.
Also, watch your form. When you get tired—and you will get tired—the first thing to go is your lower back. If you're doing a "Down" move like a deadlift, stay focused.

- Pick three "Down" exercises: Squats, Lunges, Calf Raises.
- Pick three "Up" exercises: Bench Press, Rows, Bicep Curls.
- Pair them up: Squat + Bench, Lunge + Row, Calf Raise + Curl.
- Perform 3 sets of each pair with 15 seconds between moves and 60 seconds between pairs.
- Keep your heart rate monitor on if you have one; watch how it stays elevated even during the "easier" moves.
The up and down workout isn't a fad. It’s a physiological hack. By forcing your heart to act like a cross-country courier, you’re building a cardiovascular system that’s robust, adaptable, and significantly more efficient. Stop training in circles and start training in lines—up and down.
Focus on the transition speed. The magic isn't in the squat or the press; it's in the space between them. That's where the adaptation happens. Stick with it for three weeks, three times a week. You'll feel the difference in your stairs-climbing ability by day ten. Guaranteed.
Make sure you hydrate. Moving blood that much requires volume, and volume requires water. Drink more than you think you need. Your heart will thank you for the extra fluid to move around.
