Complementary, not competitive
Let us be completely clear about the division of labour, because it protects everybody.
Your Muay Thai coach owns the fight skills. Technique, footwork, timing, clinch, defence, pad work, sparring, strategy, and any decision about whether you are ready to compete. Jack has no view on any of it and will not contradict your trainer.
Jack owns the strength and conditioning. How much force you can produce, how well your joints tolerate volume, how quickly you recover between rounds and between sessions, and whether your body holds together over a long block.
Those are different jobs and they are not in competition. The best fighters in the world have both, and the visitor doing six weeks at a camp in Thailand usually has only the first. That is the gap this page is about.
If a camp coach tells you to skip a lifting session because you are getting hammered in sparring, skip it. Fight preparation outranks strength work every time. Jack programmes as the support act, not the headline.
What strength work adds to camp training
Camp training makes you good at Muay Thai and conditions you brutally. It does a few things poorly, and those are the things worth adding.
- Maximal force production. Repeatedly performing a skill at moderate intensity does not make you meaningfully stronger. Heavier resistance work does, and force is force — a stronger hip is available to a kick.
- Structural tolerance. Tendons and connective tissue adapt to progressive loading. Kicking a bag a thousand times a week loads the same tissues in the same pattern, endlessly. Loading them differently, deliberately, builds tolerance rather than accumulating wear.
- Balanced musculature. Muay Thai is heavily front-loaded and rotational. Camps rarely do much dedicated posterior chain or horizontal pulling work, and imbalances show up as shoulder and low back complaints.
- Left-right symmetry. Almost everybody kicks harder on one side. Unilateral resistance work exposes the difference and narrows it.
- Neck and grip. Both matter enormously in clinch and neither is trained directly by most camps.
- Rate of recovery. A better-conditioned aerobic base means you recover faster between rounds, which is a technical advantage as much as a physical one — tired fighters make bad decisions.
What strength work will not do is make you better at Muay Thai. It makes you a more durable, more powerful athlete practising Muay Thai. The skill still comes from the pads.
Fitting lifting around a two-a-day schedule
A typical camp day is a morning session and an afternoon session, six days a week, often with running attached. Adding three hard lifting sessions on top of that is how people get injured or sick in week three.
The principles Jack works to:
- Two lifting sessions a week, not four. When skill training is the priority, resistance work is a supplement. Two well-placed sessions maintain and build. Four compete with recovery and lose.
- Lift on the same day as hard training, not the day between. Counter-intuitive but well established: stacking hard work on hard days and leaving easier days genuinely easy protects recovery better than spreading load evenly across every day.
- Lift after skill work, or with several hours between. Skill practice done fatigued is skill practice done badly, and it is also when people get hurt.
- Keep the lifting brief and heavy-ish. A few compound movements, moderate reps, stopping short of failure. You are not there to accumulate soreness — you have pads in the morning.
- Cut volume, not intensity, when fatigue builds. Fewer sets of the same weight preserves the adaptation. Lighter weights for more reps just adds fatigue without the stimulus.
- Drop the lifting entirely in fight week. Obvious, and regularly ignored.
If you are also managing the heat — and at a Thai camp you are — the volume ceiling drops further. See training in Pattaya heat.
Posterior chain, single-leg and neck work
Three areas do most of the work for fighters, and camps address none of them directly.
Posterior chain
Glutes, hamstrings and the muscles along the back of the hip. These extend the hip, which is where a kick and a level change come from, and they decelerate the leg, which is what keeps a hamstring intact when you miss. Hinges, bridges, hamstring curls and heavy carries. Most fighters are quad-dominant and knee-sore for exactly this reason.
Single-leg strength
Fighting happens on one leg constantly — kicking, checking, stepping, pivoting. Split squats, step-ups, single-leg hinges and lateral work build the strength and the balance in the position it is actually needed. This is also where left-right asymmetry gets found and reduced.
Neck
In the clinch your neck is load-bearing, and it is the one thing almost nobody trains on purpose. Direct neck work — isometric holds against light resistance, controlled ranges, nothing heroic — is quick, unglamorous and worth doing. Start conservatively; the neck is not a body part to be adventurous with, and if you have any history of neck injury, get it assessed before loading it at all.
Add horizontal pulling — rows in various angles — because a sport built on pushing and striking forward needs something pulling the shoulders back. And add grip: clinch is a grip contest and forearm work transfers directly.
Injury resilience for clinch and kick volume
Jack is a trainer, not a physiotherapist or a doctor. He does not diagnose, treat or rehabilitate injuries. What he can do is train the tissue that takes the load, so it tolerates more before it complains.
The usual complaints from high-volume Muay Thai training and where resistance work helps:
- Shins. Conditioning is the camp’s job. Strength work supports it by improving how well the hip and trunk sequence the kick, so the shin arrives with better mechanics.
- Hips. High kick volume asks a lot of hip rotation. Strength through the full available range beats stretching alone for keeping it.
- Knees. Usually a control problem rather than a strength problem. Single-leg work and hamstring strength both help.
- Low back. Rotational sport plus limited hip and mid-back mobility equals a lumbar spine doing work it should not. See back pain and mobility.
- Shoulders. Guard held high for hours, plus clinch, plus almost no pulling volume. Rows and external rotation work restore some balance.
See a doctor rather than a coach if you have taken a heavy head knock or been knocked out, if a joint gives way or locks, if you have numbness or weakness in a limb, if a bone is point-tender after impact, or if something has been getting worse for weeks. Concussion in particular is not a training-through injury and no coach should be making that call.
Recovery, sleep and eating during a camp block
During a hard camp block, recovery is the training variable most within your control and the one most commonly wasted.
Eat enough. Two skill sessions a day in tropical heat burns a lot, and heat suppresses appetite exactly when you need more food. Under-eating through a camp is the most common reason visitors lose strength while getting fitter. Protein sits at the upper end of the usual range — the general consensus for hard-training athletes is somewhere around 1.6 to 2.2 grams per kilogram of bodyweight daily. Carbohydrate matters here too; skill training is glycogen-hungry and low-carbohydrate dieting through a camp block goes badly. There is practical Thai-food detail on eating out in Pattaya.
Sleep. Non-negotiable and routinely sacrificed, particularly in Pattaya. Adaptation happens during sleep; short-changing it costs you the block.
Fluid and salt. You will sweat heavily twice a day. Plain water alone will not replace what you are losing on that volume of sweat. Salt your food.
Take the rest day. Most camps give one. Use it as a rest day, not as a day to add a lifting session.
Three months of Muay Thai and never lifted
This is the most common person reading this page: booked into a camp for a long stay, training Muay Thai daily, and with no resistance training background whatsoever.
You are in a good position and a slightly precarious one. Good, because you will respond quickly to strength training — untrained beginners always do, and much of the early gain comes from the nervous system rather than from new tissue. Precarious, because your daily skill volume is already high, so adding load carelessly is genuinely risky.
How Jack would approach it:
- Weeks one to three: learn the patterns. Two short sessions a week. Squat, hinge, push, pull, carry, and direct neck work. Light loads. Absolutely no maximal testing.
- Weeks four to eight: add load slowly. Same two sessions, weights climbing in small steps, still stopping well short of failure. Watch how the extra load interacts with your pad work — if sparring quality drops, the lifting comes down.
- Weeks nine onwards: build. By now you know how you recover. Volume can increase modestly, single-leg and posterior chain work gets heavier, and you will notice kicks landing harder without anybody having changed your technique.
Two sessions a week for three months genuinely changes an untrained body. It is also low enough not to interfere with the reason you came.
If your camp will not let an outside coach work on their premises — some will not, and that is their prerogative — sessions happen at a partner gym on a day pass, at your accommodation, or outdoors. Ask your camp first; it saves a conversation later.
Frequently asked questions
Does Jack teach Muay Thai?
No. He coaches strength and conditioning only. Technique, clinch, pads, sparring and any decision about competing belong to your camp coach, and Jack will not contradict them.
Will lifting make me slow or stiff?
No. That myth comes from bodybuilding-style training done to the exclusion of everything else. Strength work programmed as a supplement to skill training makes you more powerful and more durable, not slower.
How many lifting sessions a week during a camp?
Two. When skill training is the priority, resistance work is a supplement. Four hard sessions on top of two-a-days is how people get injured or ill in week three.
Should I lift on my rest day?
No. Stack hard work on hard days and keep easy days genuinely easy. Adding a lifting session to the one rest day the camp gives you defeats the point of both.
I have never lifted and I am here for three months. Where do I start?
Two short sessions a week, light, learning squat, hinge, push, pull, carry and neck work, with load added slowly from about week four. See the three-month plan.
Can Jack train me at my camp?
Ask your camp whether they allow an outside S&C coach on the premises — policies vary. If not, sessions happen at a partner gym, at your accommodation or outdoors.
Harder to break
Tell Jack your camp schedule, your lifting history and how long you are here. The strength work gets built around the skill work, not over the top of it.
