Our take
Tonal has created a proprietary digital weight system and combined this with coaching to offer a personalised and smart home gym. Its wall-mounted system uses electromagnetism to control the weights, replacing bulky and hard-to-store weightlifting equipment with a slim and sleek machine.
As well as selling the machines, Tonal sells subscriptions to personal training sessions and workout routines. The fitness landscape is shifting toward at-home equipment other similar equipment is supplied by Peloton and Mirror.
Tonal has seen impressive growth, investing equity funding into content initiatives, high-profile partnerships, scaling operations, and strong celebrity endorsements. It remains to be seen, however, if the current trend of home-workout equipment will stick around, let alone gain new momentum, but Tonal's cleverly designed equipment gives it an edge over competitors.
