The strength-training startup had a funny campaign last year, ribbing Peloton for allegedly copying the Ladder app for its Strength Plus app. Now it’s flexing that it poached Peloton instructor Jennifer Jacobs (who Peloton originally poached from Ladder) and offering Peloton members a three-month, all access subscription. Word has it Ladder is also planning to send trucks with digital billboards outside Peloton’s NY headquarters advertising the campaign.
