Best Workout Gear for Knee Up-Downs, Burpees, and Mountain Climbers

Three movements. One thing in common.

Every single rep, your kneecap contacts a hard surface.

Knee up-downs: both knees drop to the floor under full bodyweight, every rep. Burpees: the floor descent sends your kneecap into rubber or concrete at speed. Mountain climbers: sustained knee proximity to the floor throughout the movement, with repeated light contacts as the legs drive forward.

These three movements are staples of functional fitness programming. They're also the three movements most responsible for the chronic knee pain that sidelines athletes in their 30s and 40s. Not because the movements are dangerous — but because athletes do them in gear that provides zero floor impact protection.

What These Movements Have in Common (That Your Gear Ignores)

Standard compression leggings were designed for running. Knee sleeves were designed for lifting. Neither was designed for a movement where the kneecap contacts a hard floor repeatedly at high rep counts.

The fabric between your kneecap and the floor in standard leggings is 0.5–1mm of compressed nylon. Under the impact force of a burpee drop or knee up-down, it compresses completely. Your patellar cartilage takes the full hit. Every rep. Every session. Accumulating as damage that doesn't hurt until it's significant — and by then, it's already done.

The Gear That Actually Works

You need a foam pad over the kneecap. Not more fabric. Not neoprene. A pad that absorbs the impact force before it reaches the cartilage.

For knee up-downs and burpees — high-impact, high-rep floor contact — our leggings with removable knee pads are the most effective option. The compression fit keeps the pad locked over the kneecap through every rep. The high-waist design stays in place during the explosive jump phase of burpees. Remove the pad in 3 seconds for lifting days.

For mountain climbers and bear crawls — sustained floor proximity with dynamic leg movement — the same leggings work, but our training pants with removable knee pads are also excellent. The relaxed fit allows full hip flexion during the drive phase of mountain climbers without the restriction of compression fabric.

For athletes who want to wear protection over existing shorts, our knee sleeves with removable pads go over any bottoms and provide the same pad protection in a sleeve format.

Movement-Specific Tips

Knee up-downs: Lower one knee at a time rather than dropping both simultaneously. Distributes the impact across time. Dramatically reduces force per contact.

Burpees: Step one foot back at a time rather than jumping both feet back. Eliminates the impact phase almost entirely. Slower, but far less damaging over high rep counts.

Mountain climbers: Keep hips level and drive the knee toward the chest rather than letting it drop toward the floor. Reduces the frequency of floor contact during the movement.

The Compounding Math

A typical HIIT session might include 30 burpees, 20 knee up-downs, and a 60-second mountain climber set. That's roughly 70–100 floor contacts per session. Three sessions per week: 200–300 contacts. Per year: 10,000–15,000 unprotected impacts on the same piece of cartilage.

Protect the floor contact phase. Every session. The math works in your favor when you do.
