What training technique is Carlos Alcaraz using?

Alcaraz has been using blood flow restriction (BFR) bands, which temporarily restrict blood circulation in his limbs, to build muscle strength and condition his body for competition.

How does Alcaraz's use of BFR bands differ from the typical fitness application?

Alcaraz 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 his physical performance during intense matches.

What are the potential benefits and risks of Alcaraz's unconventional training method?

The BFR technique allows Alcaraz to build muscle strength with lighter weights, potentially giving him an edge on the court. However, it can also cause discomfort and may pose risks for athletes with circulatory problems, such as thrombosis.

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.
