How is TANK different from a standard friction sled or ‘prowler’?

Unlike friction sleds or ‘prowlers,’ TANK is controlled by magnetic resistance — meaning athletes don’t need to change out the weight for each user. By flipping the resistance lever, you can change the intensity of your workout without adding or removing heavy weight plates. Additionally, TANK is an all-surface weight sled with wheels, meaning it will not tear up your carpet or flooring.

One of my wheels seems low on air, what should I do?

While it is uncommon for your TANK’s tires to be low on air, if it does occur, all you need to do is pump up the tire like you would your bicycle tire, and you will be back to your workout in no time. If this doesn’t solve the problem, contact us at Torque and we can help you troubleshoot the problem.

Where can I find maintenance tips for my TANK?

There are maintenance tips included in your TANK Assembly Guide. Please check these out, as the guide answers most questions and provides tips on how to make easy adjustments to keep your weight sled rolling smoothly.

Can TANK be used as an outdoor weight sled?

Yes. TANK is coated with electrostatic paint, so you can use it outdoors, under all weather conditions, without fear of damaging the equipment. In addition, this is an all-surface fitness sled, meaning it was built to be used on a range of outdoor surfaces — from grass fields to turf tracks.

Why do football teams use TANK?

Weight sleds are particularly popular with football teams because they are centered on dynamic movement and have multi-use capabilities — ideal for a flexible team workout. TANK is perfect for engaging multiple muscle groups at once, so you can make sure your team is targeting the muscles that need the most attention for their game. Adaptable and engaging for the competitive athlete, TANK won’t allow you to coast and will push football players in a way that traditional weight sleds cannot. Learn more about why professional athletes choose TANK over other weight sleds.

What is a sled workout?

When you train with TANK you experience an intense full body workout. This innovative weight sled resists an athlete’s effort to run faster and accelerate. Basically, the faster you push TANK, the more energy you have to exert. A sled workout provides a versatile cardio workout, grounded in intense strength training.

How do you use a weight or power sled?

TANK is a versatile piece of equipment that can be used in a variety of ways. You can push or pull the weight sled, gripping a rubber-coated handle, to target specific muscle groups. Torque’s innovative magnetic resistance brake system prevents individuals from accelerating and forces them to work harder the faster they run. With four adjustable levels of resistance, you can move the lever to achieve the exact resistance you’re looking for in your workout. To switch up your training session, attach battle ropes to the tow hooks on either side of the power sled. TANK can be used on any terrain or surface.

Can TANK be used by individuals in physical therapy?

Yes. TANK is ideal for therapy or rehab purposes. This push pull sled promotes functional exercise, and its resistance capabilities allow users to build up their strength slowly over time, which prevents further injury. The resistance lever lets you target the exact level of resistance you’re after, so you can manage and control every aspect of your workout. The magnetic braking system also means that injured individuals can change the resistance level without lifting heavy weight plates on and off TANK. Torque’s weight sled is easy-to-use and safe — perfect for aging adults or individuals going through physical rehabilitation or therapy.

How do the TANK resistance and difficulty levels work?

TANK resistance is proportional to the speed — meaning that the faster you push the TANK, the more resistance there is at any level. An appropriate measurement for resistance with the TANK would be in watts.

To give you an idea of how the resistance varies depending on the brake position, we have collected some average watt readings for brake positions in the table below. All of them are taken with the axel spinning at 120 rpm, which is equivalent to someone pushing the TANK a distance of 100 feet in 16 seconds (or 4.26 mph).

Keep in mind that all of these values would decrease at a lower speed and increase at a higher speed.

Using Neutral as a baseline for 0% resistance, the difficulty will increase by these percentages/multipliers at each level of resistance:

Neutral = 0%

Level 1 = 478% increase from Neutral (478% Total Resistance Increase from Neutral) or 4.8x more difficult than Neutral.

Level 2 = 160% increase from Level 1 (1400% Total Resistance Increase from Neutral) or 14x more difficult than Neutral.

Level 3 = 36% increase from Level 2 (1933% Total Resistance Increase from Neutral) or 19x more difficult than Neutral.

With this in mind, pushing TANK on level 3 resistance is 19 times harder than pushing it at Neutral. That is roughly the equivalent of pushing or pulling a wheeled object that weighs 8,781 lbs at 4.26 mph with no resistance.

For reference, pushing TANK 100 feet on each level of resistance at 4.26 mph is the equivalent of pushing any of these objects the same distance:

Neutral – 455 lbs:  An adult male lion or TANK with 270 lbs

Level 1 – 2200 lbs:  A saltwater crocodile or a small car

Level 2 – 6370 lbs:  A blue whale’s tongue or a one-ton truck

Level 3 – 8781 lbs:  A large, adult male hippo or a monster truck

It seems that TANK is braking harder on one side than the other, is this possible?

No. The braking wheels are connected to the same axle with a solid lock. One wheel cannot spin faster than the other as they are connected by a solid 1pc axle. To verify this, simply lift the braking wheels off the ground and spin one side and try to prevent the other side from turning. If it is functioning properly, when one side turns, the other will turn at the same speed as well.

I like to watch people suffer while they do their TANK workout, and the best vantage point is standing on the weight sled while people push it. Should I ride on TANK?

While we agree it is fun to be pushed around on a sled, riding on TANK is currently not suggested. If a part of your body slips under TANK while it is moving, just like a real tank, it is going to hurt.

What is the warranty period on TANK?

TANK is built to last. There is a 10-year warranty on the fitness sled’s frame and welds, and a 1-year warranty on parts and for faulty workmanship or materials.

Do I need to change the weight on TANK for each person, depending on their ability?

No, you do not. Unlike traditional sleds, all of the resistance comes with the simple flip of the lever, thanks to TANK’s innovative braking system. Weight is only added to keep the exercise sled moving straight ahead and not veering from side to side.

How much space do I need to use TANK?

While a 30 yard run is optimal for pushing TANK, you can get a high-intensity, full-body workout in on this push pull sled with only 10 yards of space available.

What surfaces can I use TANK on?

TANK is an all-surface workout sled with wheels, meaning you can use it on any surface, including wood flooring, concrete, carpet, grass, turf, and rubber without damaging the surface.

Who uses the TANK?

TANK users include everyone from NFL, NBA, NHL, and MLB teams to assisted living communities. Because TANK trains for deceleration, HIIT, and overall conditioning while still being gentle on joints, nearly every person can benefit from training on Torque’s premier workout sled.

Why is my TANK veering to one side when I push it?

First, make sure the tires of your fitness sled are evenly inflated to 20-25 psi, as deflated tires will cause the equipment to veer from side to side. Another factor to note is that most everyone has a side of their body that is stronger than the other, which can cause the user to veer TANK incrementally and subconsciously. Keep your head up and eyes focused on where you’re pushing TANK. Making small adjustments as you push will help you keep the exercise sled moving in a straight line. This is part of training your body to be more balanced, and as you develop proper form and become stronger, you will notice the TANK staying on a straighter course.

How much does a workout sled weigh without the weight plates?

Without weight, the all-surface sled weighs 185 lbs.

How much weight should I put on TANK?

No more than 270 lbs. Adding more weight on your TANK will not increase the resistance and can potentially pop the tires and damage the equipment. All of the difficulty in pushing this weight sled comes from the variable magnetic brake system, not from the added weight.

So, why does TANK need 270 lbs?

The weight on TANK ensures you get the proper traction between the tires and the ground. You may even need less weight depending on what surface you are pushing TANK on. If you are unsure, contact the Torque team to verify!

Why does it say “Do not pull machine in position N or 1” on the side of TANK?

There is not enough resistance in N or 1 in order for TANK to stop quickly enough at those resistance levels.  With the length of the tow straps, if the user is running with the harness and stopped abruptly, it could run into them from behind.  Facing TANK with the V-Strap handles isn’t as bad because you would see it coming, but if pulling it and facing away, it could be dangerous unless someone was there to help stop it.  We recommend having a spotter assist you if you plan on using the sprint harness in N or 1.
