A common barrier to regular exercise for many individuals is a lack of time. Busy schedules can make it challenging to prioritize fitness, often leading to skipped workouts. Other barriers may include inadequate access to facilities, intimidation at the gym, or financial constraints. Additionally, some may struggle with motivation or not knowing where to start. Addressing these barriers through effective time management, finding enjoyable activities, and establishing accountability systems can help individuals incorporate exercise into their daily routines.
