Are you in charge of running a CrossFit class or organising a CrossFit program? Perhaps you are an athlete looking to compete at a higher level?

We examine the Volume vs Intensity dilemma?

The CrossFit program is built around founder Greg Glassman’s mantra of: “World Class Fitness in 100 Words” which includes the central point:

“Keep workouts short and intense.”

Greg Glassman

Any CrossFit gym owner will tell you that in the pursuit of general physical preparedness (GPP) for the general population, intensity and variety are key.

The case for increasing the number of sessions

With that in mind, why do we often see training programs piling workout upon workout for a 90 minute to 2-hour training session?

In reality these programs are not designed for those who simply want to get fit. They are designed for those who want to qualify for Regionals or for the overzealous ‘weekend competition warrior‘.

That’s not to say that volume doesn’t have its place. Firstly, volume is necessary for recovery adaptation, which in turn allows you to recover faster from workout intensity.

In other words, at a local competition that may comprise of 4-5 workouts in one day, training volume allows you to recover better between each event and hit each of those 4-5 workouts with greater intensity.

Secondly, volume allows athletes to work on multiple areas of fitness in one session (providing intensity and/or quality can be maintained).

Recovery suffers when you overdo training

However, as many of you know, volume comes at the cost of recovery.

It becomes physically and mentally challenging to maintain intensity when volume is increased.

Herein lies another benefit of volume, demanding intensity when you are physically and mentally fatigued teaches you how to perform when you are not fresh – for instance: on the final workout of a two-day competition.

Despite the potential benefits to increased training volume, mindlessly cramming workout upon workout in pursuit of fitness goals can end up stalling progress or invite injury.

Overtraining can cause a decline in performance

The most pig-headed athletes can compromise their recovery and eventually push themselves into the dreaded ‘overtraining’ zone, which often brings a regression in athletic performance.

Increased volume demands more sleep, precise nutritional habits that support performance, an injury prevention routine (massage, chiropractic work, mobility, etc.) and good communication with a coach.

It’s also important to ensure that volume does not come at the expense of intensity.

So, in theory volume can help athletes achieve success in CrossFit as a sport, but it should be implemented safely and systematically.

This is absolutely something that should be discussed with your CrossFit coach before jumping into.

Fitness for life (rather than for competition)

For affiliate CrossFit owners looking to add more volume into their classes, it’s important to remember that the majority of your members and thus the majority of your income, comes from members who are training for life.

A one-hour session four to five times a week which consists of a warm up, strength piece or skill work, conditioning, and a cool down will be more than enough to obtain fitness for life.

Trying to cram more into a one-hour CrossFit class makes it more difficult to meet your member’s needs. Don’t forget these needs include correcting, cueing and improving their movement, not simply starting the clock and saying ‘3-2-1-GO’.

As six time CrossFit Games athlete James Hobart says, “volume is not the cure-all; effective coaching is“.

Mastering the fundamentals is key

For athletes looking to add more volume into their training, it’s crucial that they have a base of mechanical proficiency in the foundational movements and they are consistent in their approach to intensity.

If you struggle with basic mechanics in movements such as the squat or with overhead mobility, then volume isn’t the solution for you.

Doing workout after workout is not a shortcut to fitness. If you lack good mechanics, it’s a shortcut to the reinforcement of poor movement.

The more you practice poor movement the better you will get at poor movement.

Top athletes strive for perfect mechanics in foundational movement and have an established training history that allow them to increase their training volume.

The intensity of workouts is king, the number is secondary

For most of us, intensity is where the magic happens.

It’s been said that excellence when training is only achieved through ‘finding that dark place in a workout and pushing further until you find an even darker place!‘.

Intensity reigns king in CrossFit and this is what separates CrossFit from the majority of other fitness programs. It’s what drives change and produces results.

Volume can certainly be used to gain the upper hand in the sport of CrossFit but it should not be added at the cost of intensity.

As a coach you should know what people in your gym train for. If it’s training for life, then there is no need for pure volume.

This group will consistently improve their work capacity with constantly varied functional movements executed at high intensity during once-a-day sessions, four to five times per week.

Any experienced coach will know this to be true; we’ve all witnessed the improvements in our charges when they commit to the program and to their fitness goals.

Be aware of the signs and symptoms of overtraining in your charges. As trainers, we should push our clients in progressive overloading but we must keep abreast of extertional rhabdomyolysis and overtraining syndrome.

Those who are looking to compete and have a solid base of mechanics as well as consistency and hit their workouts with high intensity, can then begin to look at a structured approach of increased volume in their training.
