Short answer: Yes — if the W product you mean is W (by Jake Paul) antiperspirant, it contains aluminum salts (aluminum zirconium tetrachlorohydrex Gly ~15%) and is formulated to reduce under‑arm sweating, so it will help reduce sweat during sports. (otclabels.com)

Key points to know

• How it works: Antiperspirants with aluminum salts plug sweat gland ducts temporarily, reducing sweat production in the applied area. That’s why antiperspirants (not plain deodorants) are labeled to “reduce underarm sweat.” (otclabels.com)
• Effect during sports: They often reduce normal sweating and can limit pit stains and moisture during exercise, but intense/high‑heat workouts may still produce noticeable sweat — antiperspirants lower perspiration but don’t make you sweat‑free. (Byrdie.com)
• Best use for maximum effect: Apply to clean, dry underarms (many people apply at night) and follow the product directions; nightly application allows the aluminum salts to form plugs while sweating is low, improving effectiveness the next day. Clinical‑strength or prescription antiperspirants are available for people with heavy sweating (hyperhidrosis). (Byrdie.com)
• Safety notes: OTC antiperspirants are generally considered safe for most people, but they carry usual cautions (don’t use on broken skin, consult a doctor if you have severe kidney disease, watch for irritation). If you have concerns about aluminum or persistent excessive sweating, discuss alternatives or treatment with a clinician. (otclabels.com)

If you want, I can compare W to clinical‑strength antiperspirants or suggest application timing/brands that users report work best for intense sports.
