Ever wonder how to actually use an ab roller? @brentlhill walks through the basics - how to set up, brace your core, protect your lower back, and control each rep. Once you’ve got the standard rollout down, try the around-the-world variation to challenge your core from different angles. Save this one and give it a try next core day. #bearkomplex #abroller #coretraining #abworkout #getbetter
