Jane Fonda brings her iconic workout back for a good cause on TikTok

Jane Fonda brought back her famous workout for a cause. The actress and activist, 82, resurrected her iconic Jane Fonda Workout, an ’80s VHS staple, in her TikTok debut. But she isn’t trying to get you to tighten your core, as in ab muscles — just your core beliefs. She used the video to share a message about climate change.
