Achieving sculpted, well-defined arms requires more than traditional bicep curls and tricep extensions, a muscle expert has explained.
The secret lies in understanding how both muscle tissue and fascia work together to create that coveted toned appearance.
Arlena Crouch, a licensed massage therapist and fascia specialist who founded Heavenly Hands Massage & Bodywork, explained that arm training must address both components. "I believe it's very much so a mix of both," she told GB News.

For optimal arm development, Arlena recommends incorporating dynamic compound movements alongside traditional exercises.
The fascia, a nerve-filled connective tissue that envelops muscles, plays a crucial role in determining whether arms appear firm or flabby.
This explains why some individuals experience persistent arm flab despite regular exercise routines.
"Classic exercises like pushups, tricep dips, and overhead presses are a go, but make sure to add in multi-joint moves like planks+shoulder taps, resistance band pulls, or rotational presses that engage both fascia and muscle," she advised.
These compound exercises work multiple muscle groups simultaneously while activating the fascial system.
The combination creates comprehensive upper body engagement rather than isolated muscle work.
"This combination builds strength as well as that tighter, more defined look people want," Arlena noted, highlighting how this integrated approach delivers both functional strength and aesthetic results.
Visible improvements typically emerge within a fortnight to six weeks of dedicated training, according to Arlena.
"This varies, but a general rule is that with consistency, you could start seeing changes within 2-6 weeks," she stated.
Several factors influence the speed of transformation, including dietary habits, stress levels, hormonal fluctuations and sleep quality. Arlena stressed that recuperation matches training intensity in importance.
"Your recovery efforts have to meet or beat your output," she explained, cautioning against focusing solely on muscle breakdown without adequate rebuilding.

| GETTYThe expert identified several additional training errors that can sabotage arm definition goals, including excessive focus on isolated bicep and tricep work while ignoring comprehensive upper body engagement as a primary mistake.
Poor mobility and postural alignment present another significant obstacle.
She observed that adhesions and tightness in chest fascia create rounded shoulders, comparing the resulting posture to "the hunchback of Notre Dame or The Hulk".
This forward shoulder position conceals muscle definition regardless of strength gains while increasing injury risk.
Additionally, many abandon their routines prematurely, failing to allow sufficient time for fascial remodelling and visible muscle emergence, the expert warned.
