Fitness tools for workouts, running, and progress

Make a realistic movement outline, compare running pace, or understand an exercise calculation. Every tool explains what it measures and what it leaves out.

Choose by the question you want to answer

Start moving: use the workout planner to reserve time and choose a comfortable movement preference. Explore strength arithmetic: use the one-rep max estimator with a known completed set. Plan running splits: use the pace calculator. Organize a short break: try the mobility sequence or blank interval clock. The right tool should make one decision clearer rather than produce a score you feel required to chase.

The fitness toolkit

One-rep max calculator — Use a familiar exercise, a known load and a completed set of one to ten repetitions to explore an Epley estimate. You do not need to attempt a maximum lift.

Running pace calculator — Calculate pace from a distance and finish time, or explore a finish time from a selected pace. Results include kilometer and mile conversions and even-distance splits.

Heart-rate zone calculator — Explore five illustrative heart-rate bands from an age-based maximum estimate. Choose the equation and whether the bands use maximum heart rate or heart-rate reserve.

Workout planner — Create an editable weekly outline from your experience, equipment, available days and session length. It is a scheduling aid, not individualized coaching.

Interval timer — Set a movement interval, a rest interval and a round count. Start, pause, resume or stop the silent clock whenever you need.

Mobility routine — Use a short timed sequence for comfortable shoulder, trunk, ankle and standing movements. Skip or adapt anything that does not suit you.

Plan time before increasing intensity

A schedule is most useful when it fits ordinary life. Identify available days, the minutes you can comfortably reserve and the equipment you know how to use. The workout planner separates easy preparation, a main block with breaks, and a cool-down. It does not require every available day to become a hard training day. Recovery and flexibility belong in the outline from the beginning.

Strength estimates are not tested maximums

A repetition formula extrapolates from a load and repetition count. The result depends on exercise, technique, fatigue and how the set was performed. A comfortable set stopped early does not have the same meaning as a carefully supervised near-maximal test. Use the one-rep max page to understand the arithmetic, not to select a load you must attempt. Qualified instruction is useful when you need help with technique or progression.

Pace describes time divided by distance

Running pace is an arithmetic relationship. The same pace across a longer distance creates a longer finish-time scenario, but the calculation cannot establish that you can sustain the effort. Terrain, weather, stops, fatigue and GPS error all sit outside the form. Decide whether you are using elapsed or moving time, and keep that convention consistent when comparing runs. The split table assumes even pacing.

Heart-rate equations describe averages

The heart-rate page compares two age-based maximum equations and a reserve method. It shows the formula and percentage boundaries, so different results are understandable. None of those results is a measured personal maximum or a guarantee that a band is appropriate. Medication, health conditions, measurement quality and individual variation can matter more than a small numerical difference between equations.

Warm-up, rest and progression

Use easy preparation before a more demanding activity, allow breaks and leave room for recovery. Progression is not simply adding work every day. A new or returning participant may need a smaller starting point than someone with regular practice. The site cannot observe your technique or recovery. Choose familiar movements and seek qualified advice for personal programming or restrictions. Stop for pain or concerning symptoms instead of treating a checklist as a command.

A timer gives structure, not permission

The interval timer is silent and includes Start, Pause, Resume and Stop controls. The mobility page uses the same timing approach with an optional sequence. Background tabs or suspended devices can delay updates, so keep the page visible. You can stop early, skip a movement or ignore the clock. A timer cannot assess safety, effort or a medical condition.

Where public-health guidance fits

WHO guidance provides broad context about activity and sedentary time. It is not an individualized training program. The planner records available time without certifying that a generated week meets a guideline. Total activity outside the plan, intensity and individual circumstances matter. Use the linked source to understand the broader recommendations, then seek tailored help when appropriate.

Questions people ask

Can I use these tools without an account? Yes; custom tools work in the current browser tab. Can I save a plan? Print an editable checklist or save a PDF through your browser. Can the site adapt exercise for an injury? No; generic prompts are not rehabilitation. Can I use a calculated maximum as a training load? The number is an estimate, and personal load selection requires more context.

Guides, sources and related tools

Read starting a movement routine or browse fitness guides. WHO physical activity guidance provides public-health context. It does not validate an individual exercise plan. The Nutrition hub covers meal organization, and the weekly planner combines practical reminders without pretending to provide clinical personalization.
