Centr

Chris Hemsworth's app, but the programming is genuinely good - real coaches, real progressions.

For most people who want HIIT (high-intensity interval training), Centr is the right pick because the programming is built by actual strength and conditioning coaches, not just whoever Instagram surfaced this week. The HIIT classes are properly periodized, the work-to-rest ratios make physiological sense, and the cooldowns and mobility work are not afterthoughts. Centr also bundles strength, mobility, meditation, and meal-planning into one subscription, which is convenient if you don't want six apps. If you want a free, no-equipment option, Nike Training Club is the best free HIIT library on the market. If you specifically want the Kayla Itsines BBG-style aesthetic and community, Sweat is the obvious pick. But for the "I want a HIIT class right now that won't wreck my joints and will actually progress me," Centr is the most defensible choice.

Edge cases the winner doesn’t handle as well.

App	Score	Best for	Why	Pricing
Sweat (by Kayla Itsines)	8.7	People who want the BBG community and short, structured HIIT circuits	Sweat's HIIT and BBG programs are well-known for a reason - the structure is consistent and the community is huge. Best if you respond to that aesthetic and accountability model.	$19.99/mo or $119.94/yr
Nike Training Club	8.6	People who want a high-quality free HIIT library	NTC is the strongest free option in the category, with a deep catalog of HIIT, strength, and yoga sessions led by Nike Master Trainers. No paywall on the core library.	Free
Peloton (App)	8.5	People who want live and on-demand HIIT classes with instructor energy	Peloton's HIIT, bootcamp, and Tread classes are excellent even without the bike or treadmill. The app-only tier is a strong standalone HIIT option.	App One $12.99/mo; App+ $24/mo
FitOn	8.0	People who want free HIIT classes without committing to a subscription	FitOn has a large free library across HIIT, strength, dance, and yoga. Less polished than Centr or Peloton, but genuinely free for the core experience.	Free; Pro $19.99/mo

Frequently asked questions

What is the best HIIT app for most people in 2026?

Centr is the best HIIT app for most people in 2026 because its programming is designed by qualified S&C coaches, the work-to-rest ratios are physiologically sound, and the recovery and mobility components are built in.

Is Centr really by Chris Hemsworth?

Centr was co-founded by Chris Hemsworth and is built around a team of professional trainers, dietitians, and meditation coaches. The branding is celebrity-driven, but the programming team is the substance.

Centr vs Sweat - which is better?

Centr is better if you want HIIT plus strength, mobility, and meditation in one subscription. Sweat is better if you specifically want the BBG-style program structure and the existing Sweat community.

What's the best free HIIT app?

Nike Training Club is the best free HIIT app. The catalog is deep, the instruction is high quality, and there's no core paywall on the workouts.

How long should a HIIT workout be?

Most evidence-supported HIIT protocols (Tabata, Gibala-style) run 10-25 minutes including warm-up. Centr and NTC both offer this length range, which is appropriate for most non-athletes.

Is HIIT safe every day?

True HIIT (max-effort intervals) is not appropriate every day for most people. 2-3 sessions per week with strength and easy cardio between is the standard recommendation. Centr's weekly programming reflects this.

Do I need equipment for these apps?

All four alternatives offer equipment-free HIIT options. Centr and Sweat do best with light equipment (dumbbells, mat); NTC and FitOn have strong bodyweight-only filters.
