Tennis Star Alcaraz Embraces Controversial Blood Flow Restriction Training

As of November 12, 2025, Spanish tennis player Carlos Alcaraz has been making waves with his innovative training approach. The 22-year-old sensation has been incorporating a bold and somewhat controversial technique into his workout regimen: the use of occlusion bands, also known as blood flow restriction (BFR) bands.

These straps, which Alcaraz has been seen wearing during warm-ups at the ongoing ATP Finals in Turin, are designed to temporarily restrict blood circulation in the limbs. This low-oxygen environment forces the muscles to work harder, even with lighter weights, allowing Alcaraz to build strength and condition his body more effectively for competition.

Alcaraz first began experimenting with BFR bands on his right arm earlier this year, later expanding the practice to both arms and, most recently, his legs. While the technique was initially developed for physical therapy and injury recovery, it has gradually gained popularity among elite athletes seeking marginal gains.

The Spaniard's use of BFR bands, however, goes beyond the typical fitness application. He has been employing a variation called ischemic preconditioning, where the bands are tightened more firmly to halt blood flow entirely for short bursts of up to five minutes. This rebound effect can dull pain sensations and potentially boost physical performance during intense matches.

Despite the temporary discomfort, Alcaraz seems convinced that the benefits of this unconventional training method far outweigh the brief period of numbness and tingling. As he continues to dominate the men's tennis circuit, the young star's willingness to push the boundaries of athletic preparation has become a key part of his success.
