If exceeding a certain heart rate leads to crashes, flare-ups, or days of payback, most fitness and workout apps aren’t built for you. SteadyStrength is a calm low heart rate workout and strength training app designed for people who need to stay under a personal limit. It’s built for people who already know what happens when they push too far — and want a safer way to maintain strength without setbacks. Now includes Low Energy Day sessions for days when your capacity is limited, with guided breathing, gentle movement, and supportive check-ins. You stay in control at all times. Stopping early, backing off, or resting is always okay. Workouts adapt gently based on your heart rate and how you’re feeling. Your feedback and recovery signals guide pacing and rest so you can stay within your safe zone without guessing or pushing too far. No intensity targets. No pressure. No comparison. Just steady, safe strength training that listens to your body. Why SteadyStrength is different Most fitness apps push intensity. SteadyStrength protects your energy. The focus is on calm, sustainable training — not pushing harder. What SteadyStrength focuses on • Gentle, low-impact strength exercises Carefully selected to minimise strain and support recovery-friendly training, with pacing that helps avoid post-exertional malaise (PEM). • Safe heart-rate guidance Set your personal safe heart rate, and the app helps you pace sets, rest effectively, and avoid crossing your limit. • Supportive rest screens Rest timers include breathing cues and space to log your heart rate so you can slow down and reset properly between sets. • Baseline Tracker A simple trend line that reflects how your baseline capacity is changing over time. It gently responds to your heart-rate data, check-ins, and workout tolerance — helping you notice when you’re stabilising, improving, or need more recovery. • Adaptive workouts guided by your feedback Your heart rate during workouts, along with daily or post-workout check-ins, helps SteadyStrength understand how you’re coping and adjust sessions accordingly. • Adaptive weight and workload suggestions Progression is guided by recovery signals — not pressure. If your heart rate stays calm and recovery feels steady, the app may suggest small adjustments over time. If strain shows up, it encourages backing off or taking a lighter day. • Exercise library with clear explanations Learn proper form, understand muscle groups, and filter exercises based on the equipment you have available. • A calm, low-stress experience No leaderboards. No comparisons. No pressure. • [NEW] Low Energy Day sessions Gentle, guided sessions for bad days, including breathing, one simple movement, and supportive check-ins. Especially helpful for people with • Post-viral fatigue & Long COVID • ME/CFS & post-exertional malaise (PEM) • POTS / dysautonomia • Chronic fatigue or crash sensitivity • Anyone who prefers safer, steadier workouts You stay in control. The app helps you understand your limits — not push past them. Key features • Heart-rate-guided strength workouts • Baseline Tracker showing recovery trends over time • Adaptive progression informed by user feedback • Adjustable rest timers with breathing cues • Manual heart-rate entry • Over-limit alerts • Session summaries with HR insights • Smart exercise filtering by equipment • Exercise library with safety notes • Clean, calm interface designed for pacing • Gentle progress tracking over time • [NEW] Low Energy Day sessions for recovery-focused training Strength training that respects your limits Whether you’re rebuilding after illness or simply want a safer way to train, SteadyStrength helps you move and build strength without fear of setbacks. Train slowly. Train safely. Train in a way your body can handle.
