As part of the redesigned and reimagined Bloomberg Businessweek, we’re running a monthly checklist of new products, innovations and experiences that have caught our eye.

Last month we looked at the right stuff—killer cold brew, a statement leather briefcase, the best mattress ever—to keep you on top of your game when getting back to the grind. This time around, we preview superlative solutions for when your fitness plans move indoors.

There’s no shortage of apps that tout direct access to top coaches who can fix your golf game, but HackMotion (from $295) takes it a step further by using two sensors—one attached to your wrist, the other to the back of your hand—to pinpoint problems. Unlike other options on the market that zap you with painful jolts when your swing is out of line, here you get a simple “uh-uh” audio corrective; good shots are reinforced with a pleasant chime of approval. One drill mode works while hitting live balls outside, and another allows you to practice indoors.
