In using springs for resistance, the equipment provides gradual resistance as your muscles contract, which ensures the muscles are being worked properly. There is greater resistance at the muscle's strongest point of contraction & less resistance on the initiation/completion of the contraction so there is less stress on tendons and ligaments).

Circuit training is a form of fitness training that takes the participant through a series of four to ten exercise stations with relatively brief rest intervals between each station. It is particularly useful in fitness training because it breaks the monotony of sustained training and can be performed inside, at night, or in inclement weather.

We used 12-gram transmitters on the first two birds, Sassy and Berta, in 2006, which were the lightest available at that time of the solar-powered transmitters we elected to use. The manufacturer has since pushed the state-of-the-art and developed transmitters weighing only 9.5 grams, so we now use this lighter version.

Extension and torsion springs are the two types of springs used on garage doors today. Extension springs are coiled springs installed on either side of the door above the door's horizontal track. They can be installed by the do-it-yourselfer by closely following the installation instructions and safety warnings. Torsion springs include a shaft, spring and a drum assembly, normally installed directly above the door opening.

Olympic weights have two inch holes and use the metric form of measure so they are measured in kilograms while standard weights use pounds. Most Olympic weights also have a lip on them which makes them easier to carry than standard weights.

K gold is 100% pure gold and is too soft for jewelry. Therefore, it is mixed with different alloys to increase durability and hardness. 18K gold is 75% pure gold and 25% alloys and is the least durable of the different types of golds.

While no tent weight will work under every weather condition imaginable, some work better than others and others don't work at all when the day comes that you really need them. With that in mind, let's begin with the most common tent weight materials and anchoring methods: tent stakes, rope, sandbags, concrete and steel. The obvious disadvantage with the last three is the extra weight to haul around and pay for each time you're on the road. And with sandbags they get wet and dirty.

Progressive rate springs have a variable spring rate. What this means is that the spring gets firmer as it gets compressed. The harder you push into a corner the stiffer the spring becomes. A specific rate springs features the same rate all the time, it does not matter what pressure is applied on the springs. Progressive rate springs tend to have better characteristics on the street where as a specific rate springs shines on the track.

They are made of lead shot. Lead is only dangerous if you ingest it. You never even touch the lead, just the weight bags. They are called soft weights because they can move and change shape as needed, unlike the solid weights, which can hurt you if you fall.

A "Weights Client" is an individual who participates in weight training sessions one on one with a trainer. A student is an attendee of the classes / massages.

Depending on each application, either single-rate or dual-rate springs are available. Dual-rate springs are just that-- a spring set with two separate rates. This is done with a short spring stacked on a longer spring. As both springs collapse they result in a soft, or initial, rate. The spring set will retain this initial rate until the short spring stops compressing. At that point, the spring rate "crosses over" to the stiffer, or final, rate.

The difference is both physical and operational. On a conventional spring, all the coils are spaced equally apart, except for the closed ends. In a variable recoil spring the space varies between coils with less space between coils at one end and more space between coils at the other end. The way the springs store energy is also different. For example if a conventional recoil spring is compressed 1/2", it might store 1 pound of energy.

The Tanker Series, whether the original Tanker, the Tanker XP, Super Tanker, or the new TankerT and TankerS, features a bore seal design, meaning it seals on the bore of the cylinder tube not on the rod. This is especially beneficial in extreme conditions. Since the sealing surface is never exposed to the outside environment, the Tanker Series performs exceptionally in demanding applications.

Superide springs are designed to yield the best possible ride quality. Heavy-duty springs are designed for use on vehicles equipped with accessories that add a significant amount of weight, such as a winch or snowplow, or vehicles that are subject to extreme use.

Not typically. There are times when we provide weights, but most of our strength training is done with resistance bands, medicine balls and body weight, similar to what is commonly seen in gyms or physical therapy centers.
