"What routine should I do?"

Your optimal workout split is the one that matches your physique goals.

Stop agonizing over whether you should do Push/Pull/Legs, Upper/Lower, full-body, a bro split, or some custom mashup of them all.

To find your best split, start with a better question: What do you want to grow most?

One lifter wants a bigger chest and wider delts. Another wants great glutes and couldn’t care less about chest. They shouldn’t be doing the same routine. And they shouldn’t be following a routine that treats every body part equally.

The Split Stream specializes your training to develop the muscle groups that matter most to you.

Priorities

Your best split starts with your priorities.

You choose how important each muscle group is to you by adjusting priority sliders. Set a muscle high if you want to emphasize it. Set it low if you only want to maintain it. Set it to zero if you don’t want to train it at all.

Then Rep Loader builds your training stream around those priorities.

High-priority muscles receive more set volume. Low-priority muscles stay closer to maintenance volume. Your finite recovery resources go where they matter most.

Readiness

Train muscles when they are ready.

Rep Loader doesn’t just divide body parts across the week. It distributes your training volume based on priority, recovery, and readiness.

High-priority muscles are trained again as soon as they have recovered, grown, and are ready for another productive stimulus. For some muscles, that may be as little as 48 hours later.

The goal is a training stream that keeps your most important muscles growing continuously, without overdoing it.

Recovery

Walk the razor’s edge of recovery.

Optimal growth happens near the edge of recovery. Not below it, where you leave gains on the table. Not beyond it, where fatigue accumulates faster than you can adapt.

Rep Loader monitors your performance for signs that a muscle group may be under-recovered. When it detects a pattern, it can reduce volume, trigger a deload, and adjust the stream until you recover.

The goal is simple: Push hard enough to grow. Recover well enough to keep growing.

Adaptability

Fine-tune your program on the fly.

Getting pain in your shoulders? Dial down your Front Delts until you feel better. Summer on the way? Get ready for shorts weather by turning up the volume on your calves.

With Split Stream, you can fine tune your workouts and see instant changes in the volume and frequency of the work. No need to go back to the drawing board every time you want to make an adjustment.

Training every muscle group equally makes sense if you want equal growth everywhere. For lifters who want to specialize, there's Rep Loader.

Split Stream FAQ

Your training.
On your schedule.

What happens if I miss a day?

You can’t miss a day in a split that isn’t tied to the weekly calendar. Whenever you return, the next workout contains the best exercises for your stated priorities and training history. Missing “leg day” doesn’t mean skipping legs for the week. Just do the next workout. You’re free from the Monday-to-Sunday reset.

When do I take days off?

Whenever your schedule calls for it—and whenever your body needs it. Take the rest you need, then pick up with the next workout. If you train more than six days in a row, your coach will give you a gentle reminder to pay attention to recovery.

What is High Frequency / High Intensity Training?

Rep Loader is built around a simple idea: your best growth comes from hard, high-quality sets performed while the muscle is fresh enough to produce real tension.

Instead of crushing a muscle with one huge session full of junk volume, Rep Loader spreads your weekly volume across repeated growth exposures. For high-priority muscle groups, that usually means 8 hard sets every 48 hours.

That number matters.

Eight hard sets is enough to create a serious growth stimulus when those sets are taken close to failure. But it is not so much volume that recovery gets buried for days. The goal is to stimulate the muscle as soon as it’s finished growing and recovering to enter a state of continual growth. We’re not claiming that Rep Loader guarantees to put you in that state, but that is the north star that guides our development.

Won’t high-priority muscles be overtrained if they show up every 48 hours?

Not if the volume is distributed intelligently. Rep Loader is not asking you to smash a muscle with 16 hard sets, then come back 48 hours later and do it again.

Instead, it can split that same weekly volume across more frequent exposures. The total volume is similar, but the quality of the work is usually higher because more sets happen while the muscle is fresher.

As a backstop, Rep Loader monitors performance for signs of overtraining. If your numbers start dropping, the system can reduce targets, adjust workload, or trigger a deload.

Can I skip leg day?

Yes. If you set quads, hamstrings, glutes, and calves to zero, they will stay out of the stream. I don’t recommend ignoring entire body parts forever, but Rep Loader gives you the option.

We hope you won’t need to. Rep Loader distributes lower-body work more intelligently, so leg day doesn’t have to become one giant punishment session. More likely, you’ll be doing hamstrings alongside non-leg muscles, like side delts, traps, or triceps, to ease the pain.
