Overtraining is a serious threat especially for professional athletes. Deciding the optimal training intensity based on your gut feeling is not very reliable, but data is. EMFIT QS with +ACTIVE subscription provides powerful and automatic sleep and recovery tracking that will help you optimize your training intensity to maximize your sports performance. Hidden under the mattress, it is the only wellness monitor on the market that can provide you whole night heart rate variability (HRV) data for your recovery and readiness analysis, without you wearing anything. That makes EMFIT QS the preferred choice for so many athletes. It is the secret weapon that will help you lift your sports performance to new heights. This is where the journey towards your highest potential begins.

Forget about the burden of wearing a device to bed and endless charging

Whole Night Heart Rate Variability

Optimize your training to maximize your performance

Research links high HRV to good health and an optimal level of fitness, while decreased HRV is associated with stress and fatigue. EMFIT QS is the only non-wearable sleep and wellness monitor on the market that can provide data for accurate recovery and readiness analysis based on whole night HRV. Whole night HRV gives you a very detailed picture of the progression of your recovery and readiness for training. Evening HRV shows accumulated stress over the day, while morning HRV indicates your recovery status and readiness for a new day. With this insight, you can optimize your training intensity according to the actual requirements of your body, avoid overtraining and push yourself right to the limit.
