optimize your workout with w2nd


W2ND helps you take your workout to the next level! W2ND is everything you'd expect from a heart rate monitor and more. Using advanced digital signal processing, W2ND can detect your lactic threshold without having to draw blood!

Lactate threshold workouts like HiiT (high intensity interval training) are beneficial for everyone, from those trying to lose weight to those that want to beat their best marathon time.

 

Weight Loss


When you hit LT, your body begins to metabolize energy (fat, sugars, calories) 10x faster. Anaerobic metabolism is known to burn energy at a much higher rate to maximize the amount of energy available during your workout.

 

Athletes


Your LT is the maximum your heart before your blood lactate levels begin to build up. This leads to fatigue of the muscles, causing you to burn out during an activity.

 

Knowing where your LT is will help you set your pace so you won't burn out. Working out using LT workouts will help improve your LT so you can increase your pace!


Satisfied users of W2ND includes elite cyclists!

Accuracy


Non-Medical ECG

Ever wonder how accurate your heart rate monitor is? With W2ND, you can be sure you’re receiving the best quality signal. Use the non-medical ecg screen to verify that your heart rate signal is coming in clean. Then move over to our workout page and you’ll be able to track your heart rate and keep an eye on your cadence, no matter the activity!

HRv


Heart Rate Variability

  • An increase in HRV represents a positive adaptation/better recovery status,
  • A reduction in HRV reflects stress and a worse recovery status.

HRV can accurately measure the balance between SNS and PNS and can do so in a non-invasive manner through the use of non-medical ECG analysis. HRV is commonly used by exercise scientists to monitor systemic fatigue and recovery. HRV can help identify the following:

  • Accurately reflect recovery status;
  • Help determine if an athlete is overtraining;
  • Identify when the athlete may be more or less adaptive to training, thus aiding in training prescription;
  • Predict whether an athlete may perform better or worse on a particular day;
  • Predict when the athlete is more susceptible to illness or injury.

 

W2ND Tip: check HRV first thing in the morning upon waking (before coffee or breakfast) -- this is the most effective time to test. The test will take just a couple minutes and the values will be recorded by the app -- also take a screenshot for good measure. Do this every day, same bat time, same bat channel. After about 10 days, an individual specific baseline value/normal range for HRV will be established.

A use for all



lactate threshold


Each person has a different heart rate at their lactic threshold. Lactic threshold can be described as the maximum heart rate at which lactic acid is transferred out of the blood stream. When a person is working out above their lactic threshold, lactic acid builds up in the blood stream and the person begins to burn out. LT training can provide a couple of benefits. The first benefit is improving a person's maximum heart rate. If the heart can pump more oxygen to the muscles and keep the lactic acid levels low, burnout will not happen nearly as fast. The second benefit is in weight loss. As the heart hits LT, the body switches into anaerobic exercise. During anaerobic exercise, the body begins to burn energy (fat, sugar, and calories) at a much higher rate. This stems from the "fight or flight" response, allowing the body to have access to all the energy it could possibly need.

 

Improve the max, burn calories, burn fat. 

Diastolic stepping


Get your second wind by perfecting the diastolic stepping technique. Diastolic stepping is when an individual's heart rhythm is in sync with their cadence. Essentially, this makes the body more efficient during those long distance runs and rides.
