Tom Holland’s Cindy Workout: What Buyers Should Know Before Training

A simple bodyweight routine has gained fresh attention after actor Tom Holland revealed it as his go-to exercise when time is limited. The workout, known as “the Cindy” in CrossFit circles, consists of just five pull-ups, ten push-ups, and 15 air squats performed repeatedly for 20 minutes. While the movements sound straightforward, fitness experts confirm that this routine delivers serious results for outdoor athletes, runners, climbers, and hikers looking to build functional endurance.

Holland told Men’s Health UK that his personal record stands at 27 complete rounds of the sequence in 20 minutes, with a minimum of 20 rounds even on his most demanding training days. For context, CrossFit standards suggest that intermediate athletes typically achieve eight to ten rounds, making Holland’s performance exceptional. However, even beginners and intermediate fitness enthusiasts can benefit significantly from incorporating this workout into their training regimen.

Why the Cindy Matters for Your Fitness Goals

The appeal of the Cindy lies in its simplicity and versatility. You need no equipment beyond a pull-up bar and the ability to move your own bodyweight. The routine trains muscular endurance, which refers to your muscles’ capacity to sustain effort over extended periods while maintaining proper form. This translates directly to outdoor activities where continuous movement with stable technique is essential.

The upper-body exercises in this workout, specifically pull-ups and push-ups, activate the shoulders, chest, arms, back, and core. Pull-ups demand you move nearly 100 percent of your bodyweight against gravity, while push-ups require approximately 75 percent of your body weight. These aren’t light movements, even without external weights. For climbers, paddlers, and swimmers, this upper-body focus proves particularly valuable, as these activities rely heavily on pulling and pushing strength developed over extended periods.

The air squats component addresses your lower body, engaging the quadriceps, glutes, and surrounding stabilizer muscles. Though squats feel less demanding than pull-ups, completing ten rounds means executing 150 total squats by the 20-minute mark. Your legs will likely experience significant fatigue, making this portion highly relevant for runners and hikers who need durable leg strength for extended outdoor pursuits.

Building Practical Strength for Outdoor Activities

What distinguishes the Cindy from other strength routines is its emphasis on performing high repetitions consecutively. This approach develops functional endurance rather than pure strength peaks. When you’re hiking steep terrain, climbing rock faces, or running long distances, your muscles must sustain effort across many repetitions without form breakdown. The Cindy replicates this demand in concentrated form.

Many athletes find that integrating this workout into their existing routine requires minimal time commitment while delivering maximum return. You can perform the Cindy once or twice weekly as a complement to sport-specific training. Consider pairing it with quality workout shoes designed for your primary activity, which can improve stability and reduce injury risk during high-repetition movements.

Mental resilience forms another critical component of this routine. After several rounds, your muscles and cardiovascular system will signal that stopping is preferable to continuing. Pushing through that discomfort, provided you maintain safe form and appropriate intensity, conditions your mind for the mental toughness required during outdoor adventures. This psychological benefit often gets overlooked in conventional training discussions but proves invaluable when facing genuine physical challenges outdoors.

Getting Started with the Cindy

Before attempting the full 20-minute version, assess your current fitness level. If pull-ups pose significant difficulty, begin with assisted pull-up variations or resistance bands. Modified push-ups on your knees or an incline surface can also serve as reasonable starting points. You might also explore strength assessments to gauge readiness for advanced workouts before jumping into demanding routines.

Start by completing three to five rounds at a comfortable pace, then gradually progress toward more rounds as your fitness improves. Form always takes priority over speed or round count. Rushing through sloppy repetitions increases injury risk without building the muscular endurance you seek.

The Cindy demonstrates that effective training doesn’t require expensive equipment or complex programming. A straightforward, time-efficient routine performed consistently can meaningfully improve your capacity for outdoor pursuits. Whether you’re preparing for a challenging hiking trip, improving climbing ability, or simply building overall athletic resilience, this workout offers a proven path forward. Proper footwear and apparel, such as well-designed workout shorts, enhance comfort during high-repetition sessions and support your training consistency.
