Electrical muscle stimulators in the form of transcutaneous electrical nerve stimulators (TENS) or neuromuscular electrical stimulators (NMES) are expensive devices with manufacturers who justify their costs based on claims that they can improve strength, recovery and healing from injury.

In my continuing series looking at the controversies raised by the Netflix documentary the Game Changers I speak to a professional triathlete with an impressive track record and a diet that includes animal products. We did not get this perspective in the film so Chris Leiferman brings it here. Finally, Reels for wheels has two new film recommendations to help you get through your winter trainer rides.
