Key facts
The shoulder, lower back, knee and elbow are the most injured areas across the weight-training sports.
43% of competitive powerlifters report problems during routine training.
Soreness after heavy or unfamiliar work peaks 24 to 48 hours later.
Heat after training supports recovery and supports sleep. It does not prevent injury.
01

Every lifter pictures the one that pops.

The bar that drops. The tear you hear. That is not what stops most lifters.

Across the weight-training sports, the shoulder, lower back, knee and elbow are the most commonly injured areas, and the most common injuries are strains, tendinitis and sprains. In 245 competitive and elite powerlifters, 43.3% reported problems during routine workouts, at about one injury per 1000 hours of training. In 71 competitive bodybuilders the figure was 45.1%. Almost half of the lifters in those groups were training through something.

A systematic review put the rate at 2.4 to 3.3 injuries per 1000 hours of training in weightlifting and 1.0 to 4.4 in powerlifting, with the spine, shoulder and knee the most common sites. The same review noted that almost nothing has been published on why it happens.

It rarely happens under the bar. It happens in the weeks around it.

It's not an injury yet. That's the problem.

It is the Wednesday press that felt heavier than it should, because Monday's squats were still in your legs.

The last set you cut to three reps. The warm-up that took twice as long. The week your shoulder felt tight overhead, so you trained through it.

Nobody can tell you for certain why. A 2018 review of powerlifting injuries points at heavy loads, a large range of motion, not enough rest between sessions and technique that slips, and is careful to call them suggestions rather than findings. What is documented is that lifters over 40 get hurt more often in the upper body. None of it goes in your log. By the time it has a name, it has been there for a month.

03

A few minutes of stretching. A massage gun in a drawer.

You stretch your hips against the rack while the bar is still loaded. You bought the massage gun. You foam roll when something already hurts.

You sleep badly after a heavy session and train again the next morning.

That is not a criticism. It is what almost everyone does.

Your sessions have a time in your week. Recovery gets whatever is left over.

Not a gym sauna

In a crossover trial, 16 male basketball players did a maximal strength and plyometric session, then either sat in an infrared sauna for twenty minutes or rested.

After the sauna their jump performance dropped less, their muscle soreness was less severe and they rated their own recovery higher. Sixteen people is a small study and it is the best one that exists on heat after lifting. Read it as a reason to try it, not as a promise.

This is not instead of training. It is the fifteen minutes after.

Where the heat actually goes.

A gym sauna heats the air around you. Full spectrum infrared warms your body directly, the quads, the back and the shoulders you just loaded.

Your heart rate climbs. Your blood vessels open. You sweat. In one lab study, heat that warmed the muscle itself raised blood flow in that muscle, while simply raising core temperature did not.

The bonus

The hardest part of red light therapy is standing in front of it.

You're already sitting down.

A panel costs three hundred to two thousand dollars on its own, and the protocol is standing still in front of it several times a week. Nobody does that after a heavy session. You will sit down after one.

It is in the back wall. Not an upsell, not an attachment, not a subscription.

Most owners land on four or five sessions a week. Put it after the heavy days and leave the rest alone.

For a lifter that is just every heavy day.

Best purchase I've made

I’m in it 4 to 5 nights a week, specifically after a decent lifting day. Sleep better, fall asleep faster, DOMS reduced. Pre-heating it for about 15 minutes is the key to getting it really hot.

Worth the price

Relatively easy to setup, it looks great in my basement home gym, and it’s HOT. The red-lights are a great added feature. I’ve been in many wooden infrared saunas that don’t feel this hot.

This was a good buy

From sitting in the saunas at the gym to finally being talked into buying the SaunaBox, I didn’t think it would be hot enough. I was wrong, I have not been able to use it at the hottest level yet. One down side, it is tight, not much room to move.

Up to 158°F, and the range starts at 77°F, so you can sit cooler on a day your session has already taken enough out of you. It ships set to 149°F; holding TIME + and TIME − together for about six seconds unlocks the full range.

About fifteen minutes. Turn it on before your last set and it is ready when you rack the bar.

Drink water first and start with shorter sessions. Heat straight after heavy training is extra load on the body for the first week or two.

Rest, food, water and sleep do most of the work. Heat afterwards supports recovery and supports sleep, and fifteen minutes is enough.

Across the weight-training sports the shoulder, lower back, knee and elbow are the most commonly injured areas, and strains, tendinitis and sprains are the most common injuries.

In one small crossover study, 16 players who sat in an infrared sauna for twenty minutes after a strength session reported less soreness and better recovery the next day. It supports recovery. It does not prevent injury, build muscle or add strength.

35 by 37 inches of floor and 63 inches tall, so it clears a standard doorway and sits in a corner. Measure the tightest turn on the way in, not the room. It arrives as two flat boxes, the larger 65 by 37 by 13 inches.
