The KISS Principle: Why Simple Training Actually Works

There is a version of cross-training culture that equates effort with elaborateness. More drills, more variations, more moving parts, as if a programme has to look complicated to be doing its job. I want to make the case for the opposite this month, because it is the principle I keep coming back to in my own training and in how I coach: keep it simple, stupid.

What "simple" actually means in programme design

Simple does not mean fewer results. It means removing the unnecessary complexity that gets mistaken for progress. A programme built around a handful of well-chosen movements, done consistently, with clear intent behind each one, will outperform a scattered mix of exercises that look impressive but do not build anything specific. Simple is a design choice, not a shortcut.

For aerialists, this matters more than most. You are already asking your body to learn complex, high-skill movement on the apparatus. Your off-apparatus training does not need to compete with that complexity. Its job is to support it: build the strength, joint control and tissue resilience that make the skill work possible and sustainable. That is a focused job, not a sprawling one.

This is backed by what the research on ring and inversion-based strength actually shows. A recent review of shoulder mechanics in aerial acrobatics found the shoulder girdle accounts for somewhere between 24% and 55% of all injuries in the sport, a notably higher rate than in related disciplines like rhythmic gymnastics (around 18%) or swimming (around 22%) [1]. The same review points to the most effective prevention strategies being narrow and specific: eccentric strengthening of the external rotators, scapular stabiliser training, and progressive load increases capped at roughly 10% per week. Not more exercises. Fewer, better-chosen ones, applied consistently.

Separately, research into preparatory strength for static ring holds, like the inverted cross, found that just two exercises, an overhead press and an inverted position with dumbbells, correlated strongly with strength in the actual skill [2]. Elite athletes were not doing dozens of accessory movements. They were doing a small number of exercises very well, tracked against clear strength benchmarks, and letting technique training handle the transfer to the actual skill.

Why over-programming is a trap

Over-programming tends to catch the people who care the most. If you are motivated and invested in your progress, it is tempting to believe that adding more will get you there faster. More conditioning, more mobility work, more accessory exercises stacked on top of an already full training and teaching schedule. In practice, this usually produces the opposite of progress: fatigue that never fully clears, inconsistent execution because nothing gets enough focused attention, and a nervous system that stays in a low-grade state of "too much" rather than one primed to learn.

The fix is not doing less because you are lazy or unmotivated. It is doing less because you have decided, deliberately, what actually matters right now, and you are protecting your capacity to do those things well.

The KISS principle, this month's throughline

This is what I mean by the KISS principle: identify the smallest set of consistent inputs that reliably move you forward, and hold that steady rather than constantly adding to it. It is not about ambition versus laziness. It is about recognising that consistency compounds, and complexity often just creates noise that gets in the way of that compounding.

A live example: keeping my own training simple through perimenopause

I am living this principle right now, not just teaching it. Perimenopause has changed how my body responds to load and recovery, and if I am honest, my instinct earlier in my career would have been to solve that with more: more mobility work, more corrective exercises, more of everything stacked into an already full week of teaching and coaching.

There is a physiological reason that instinct backfires now. Research into perimenopausal connective tissue shows oestrogen receptors are present in tendon and ligament tissue, and as oestradiol fluctuates and declines through this transition, collagen synthesis and tendon stiffness can shift with it [3]. Recovery capacity narrows too: hormonal shifts through this transition are increasingly linked to slower tendon repair and reduced structural resilience, which lowers the amount of training stress the body can actually absorb and adapt to at any given time [4]. More inputs do not solve a narrower recovery window. They just compete for a smaller amount of capacity.

So instead, I have pulled my own training back to fundamentals. A small, consistent set of movements, held steady rather than added to, is doing exactly the job I need right now: building strength where I actually need it, giving me a clear, honest readout of how my body is responding day to day, and not demanding recovery capacity I do not currently have. I am not doing less because I have given up on progress. I am doing less, more precisely, because that is what is actually working.

Where the Straight Arm Invert Lab fits

This is exactly the gap the Straight Arm Invert Lab (SAIL) is built to close: a structured, uncomplicated way into consistent straight-arm and invert-specific conditioning, without you having to build or guess your own programme from scratch. It draws on the same principle the research supports, a small number of well-chosen movements, progressed deliberately, rather than an overwhelming stack of exercises that never gets trained with enough focus to actually work. If the idea of a simple, sustainable approach appeals to you more than another complicated plan you will abandon in three weeks, SAIL is where I would point you.
