OnCrux Liquid Climbing Chalk Helps You Get a Grip

Visit any climbing gym or outdoor climbing area and you’ll see the same scene: athletes with white chalk coating their hands, clothing, even streaked across their faces. Adding to this problem, chalk bags commonly explode when stuffed in a pack leaving moisture-absorbing magnesium carbonate dust everywhere. Seeking a lower-mess chalk solution, several companies have been experimenting with liquid chalk.

The usual alcohol base dries the skin and helps the chalk mix stay on hands, but still didn’t manage to stop chalk dust from covering clothing. So while gyms aren’t left with a dusty haze, climbers’ hands still leave an imprint on everything they touch.

This year OnCrux is taking that quest one step further with its new Cruxgrip Liquid Chalk—which stays on your hands and off your clothes.

“It gets into all the holes in your hands and blocks the sweat glands,” says OnCrux chemist and co-founder Michael Doan. “This way, when you touch other things, there’s minimal transfer. It’s also a good thing for gyms because it reduces the dust levels and doesn’t clog air filters.”

To get his formula just right, where it wouldn’t separate on the shelf or wipe off on clothing while, most importantly, doing its real job of providing optimal grip, Doan went through months of trial and error. “You do it over and over until you find the right ratios,” he says. “I ran 50 to 100 tests before I got it right.”

With a 70 percent alcohol base, Cruxgrip Liquid Chalk is strong enough to be used as hand sanitizer, which can also be useful to help slow the spread of COVID-19 since climbing requires putting hands and feet on whatever terrain climbers ascend.

Though Liquid Chalk works as a standalone product, it’s most commonly applied as a base—before adding a very thin layer of dry chalk, such as Cruxgrip Powder Chalk. This is an especially important combo when it comes to competition climbing, says OnCrux co-owner Glen Suh. “If you’re not base-coating and layering loose powder, you have a disadvantage. You get a better grip on the holds. The liquid chalk helps the loose chalk stay on your hands.”

Climbing is notoriously hard on the hands. Each time your hand slips ever so slightly (and frequently) on a hold, skin gets scraped. On demanding routes, where sharp edges dig into fingertips, the damage is that much worse. For minor scrapes and sore hands (and feet), OnCrux developed Cruxcare Handsalve. Like with Cruxgrip Liquid Chalk, the hand salve is fast-absorbing and doesn’t leave a residue on everything you touch.

Despite liquid chalk’s growing popularity, “most people still don’t know what it is,” says Suh. Of those who do, “about 90 percent of them say they like it,” he adds.

For those 10 percent naysayers—mostly gym route setters—who believe liquid chalk doesn’t do enough to dry their hands, OnCrux plans to release its Performance Liquid Chalk next year, which will include additional drying agents.

“It’ll have more coverage and dry twice as fast,” promises Doan, “so you can use less and get even more out of it.”

Best Time-Under-Tension Workout for Total-Body Strength

Published

on

Barbell Back Squat


The key to 360-degree muscle: 90-degree eccentric isometrics. It might seem like we’re throwing a lot of geometry at you, but the concept behind time under tension (TUT) is simple, says Joel Seedman, PhD, owner of Advanced Human Performance: “Perform the lowering phase of a movement in a slow, controlled fashion, usually 3 to 5 seconds; pause in the stretched position, typically around 90 degrees; then perform the lifting phase in a powerful yet controlled fashion.” Believe us, a time-under-tension workout can humble even seasoned lifters…Eccentric isometrics are like the pressure cooker of training.

“Rather than mindlessly performing slow-tempo reps, you’re using the increased time under tension as a means to fine-tune your body mechanics and alignment, which requires more mental engagement and focus,” Seedman adds.

If you want to forge functional muscle mass and strength while simultaneously bulletproofing the joints and connective tissue, give this 10-move, full-body eccentric isometrics workout a go.

Directions

Perform the following moves as 90-degree eccentric isometrics following the above protocol. Use heavy weight, but not at the detriment of proper form. Rest 60 to 90 seconds between sets and 2 minutes between circuits. Perform once every 2 to 4 days for optimal results.

Circuit 1

Marius Bugge

A. Barbell Back Squat

Set a squat rack up with heavy weight, then grasp bar and step under it. Squeeze shoulder blades together, then stand to unrack bar and step back with feet shoulder-width apart. Inhale, hinge at hips and slowly bend knees to 90 degrees. Pause, keeping natural arch in low back, then extend through hips to powerfully stand. 3 x 4-6 reps

Start in the top position of a pushup with hands shoulder-width apart on moderate-to-heavy dumbbells (shown). Explosively drive right elbow back to row dumbbell toward ribs while balancing on opposite hand and feet. Pause, then slowly lower weight, stopping a few inches above floor. Switch sides after all reps are done. 3 x 5 reps each side

A. Dumbbell Bentover Row

Stand with feet hip-width apart, holding two moderate-to-heavy dumbbells in front of thighs, palms facing you. Push hips back and hinge torso forward so it’s nearly parallel to floor, soft bend in knees. Dumbbells should be near shins. Drive elbows back to row weights toward ribs. Pause, then slowly lower down for 3 to 5 seconds. 3 x 4-5 reps

Stand lunge-length in front of a flat bench, holding heavy dumbbells in each hand by your sides, palms facing in. Rest the ball on top (shoe’s laces) of your right foot behind you on the bench. Slowly lower your body until your front thigh is parallel to the floor. Pause, then drive through your heel to stand. Switch sides after all reps are complete. 2 x 3-4 reps each side

B. Single-leg Romanian Deadlift

Stand with feet hip-width apart holding dumbbells or kettlebells. Drive right leg up, foot flexed, knee aligned with hip, making a 90-degree angle. Hinge at hips as you slowly lever your torso toward floor, lowering weights and driving right leg back for counterbalance. Hold, then squeeze glutes to reverse. 2 x 3-4 reps each side

Circuit 4

A. Pullup

Hang from a pullup bar using an overhand grip with legs extended and feet flexed. Engage lats and draw shoulders down your back, then pull yourself up until chin is higher than hands. Pause at the top, then slowly lower. Pause at bottom, then reset before your next rep. 2-3 x 4-5 reps

B. Kneeling Overhead Barbell Press

Hold a bar with moderate-to-heavy load at shoulder level with forearms perpendicular to floor. Kneel at end of bench with feet flexed to grip edge for support. Inhale, engage your core and glutes, then press the bar overhead, pushing your head forward so it passes your face, exhaling at the top.
Slowly lower until elbows are at 90 degrees, then hold to maintain tension. Begin your next rep from here. 2-3 x 4-5 reps

Circuit 5

A. Dumbbell Pushup

Place hands on dumbbells (this provides greater range of motion) at shoulder width and feet wider than shoulder width with just toes touching the ground. Keep head neutral and hips high to increase tension on core, chest and tris and reduce stress on spine. Slowly lower to the floor. Stop
once elbows hit 90 degrees, pause, then push up to start. 1-2 x 6-8 reps

B. Biceps Curl

Stand with feet hip-width apart with moderate-to-heavy dumbbells in each hand hanging by sides. Engage biceps to curl the weights up, keeping upper arms still. Pause at the top, then lower slowly. Don’t let arms drop all the way down to keep greater time under tension on biceps. 1-2 x 6-8 reps
