Mixed modal

Four hard sessions, one week.

CrossFit asks for output across every energy system, several times a week. The stack is about the fourth session being as good as the first.

The repeatability problem

Everyone's good on Monday.

Mixed-modal training accumulates fatigue faster than any single discipline. What counts is how the last session of the week compares with the first.

Saturation, hydration and a stimulant strategy you can sustain are what hold the week together. Protein handles the rest.

The essentials

The box stack.

Creatine and hydration are the daily base. Caffeine is a tool, used on the sessions that need it.

Output science

The science of repeatability.

Three things make a week repeatable: creatine saturation, hydration and a planned stimulant strategy.

Phosphocreatine
01 · Saturation
Phosphocreatine

Short maximal efforts run on the phosphate system, and creatine keeps it topped up between them. That is most of what a metcon asks for.

✓5g creatine daily
✓Electrolytes in the scoop
Fluid and salt
02 · Hydration
Fluid and salt

Even a small drop in body water can reduce output, and in a warm box in summer that can happen within a class.

✓400mg sodium
✓Five electrolytes
Caffeine strategy
03 · Stimulus
Caffeine strategy

Caffeine works until tolerance and sleep debt take the gains back. Reserve the high-stimulant option for one or two sessions a week.

The protocol

The class day.

One pattern that holds up whether it is a strength day or a chipper.

01 · Morning AM
Saturate

5g of creatine with breakfast, every day. When you take it matters less than not missing a day.

Hybrid Creatine

CrossFit supplements

CrossFit favours the athlete who can repeat quality sessions. This stack is daily creatine for repeated efforts, a five-salt electrolyte profile for warm classes and a caffeine plan you can sustain.

All products are made in the UK in an ISO 22000 certified facility, with the dose printed on the label.

Before you buy

Questions, answered.

Creatine. It works in the background every day, whereas pre-workout only helps the session you take it before, and stops helping if you take it daily.

You may hold a kilo or two of water in the muscle. For work on the sled and the barbell, the extra output is usually worth more than the weight. If bodyweight is part of the skill, factor in the kilo or two.

Take electrolytes and carbs between sessions and protein after the second, and keep caffeine to the first. Sleep is usually what limits you.

The Sauce is made in the UK to ISO 22000 standards with every dose on the label. Efectiv products are not Informed Sport certified, so check your governing body's rules before using any supplement in a tested sport.
