iFour Core vs Chakra Cycling

Every individual’s anatomy is different which is why we have designed a customizable, physical therapy approved core program. The iFour Core app addresses specific areas of your core to help you develop the strongest core imaginable without injury. Each workout is under 10 minutes, is suitable for all fitness levels, and can take place in the home or at the gym. As a member of the iFour Core app, you will receive new workouts every day, nutrition guides, and support. FREE 7-day trial for new members! HOW IT WORKS: After completing the iFour Core fitness test, you will get a core strength rating. This rating is broken up based on muscle fibers worked (intrinsic, rectus, obliques & transverse). The iFour Core app customizes the exercises each day based on your fitness test performance and current level of core strength. WHAT MAKES US DIFFERENT: Life is full of surprises, plateaus, and challenges. We created this app with this in mind allowing you to recalibrate your individualized workout formula at any point you feel necessary. Unlike other programs, this is not simply just hitting “reset,” and repeating the same exercises from previous days. This is a full recalculated algorithm taking you from your new “starting point” with a proven plan of attack to help you once again improve. iFour Core Features: Workout & Fitness Planning • Functional yet challenging core rotations, ranging from 5-10 Minutes! • Includes regressions to decrease difficulty and progressions to advance the exercises as you improve. • 323 unique core exercises. • 137 additional core exercises with 6 different pieces of equipment to choose from. • Video demonstrations of all 323 core exercises. • Designed for all levels, whether you are coming out of physical therapy or an elite athlete! • Take the fitness test and as you get stronger, unlock more core exercises prescribed for you. Tracking & Fitness Motivation • Workout along with J, a seasoned trainer for celebrities, professional athletes, and others. • Track your daily progress in both your Fitness Test and Workout History. • Share your results on your favorite social media platform. • Keep up to date and learn with the latest iFour videos.

Train for the ride that matters. Chakra builds a personalized cycling training plan from your real Strava rides — and adapts every week as you log new efforts. Pick a goal. Tell us about you. Get a plan that actually fits. Three ways to set a goal • Train for a race — choose from 32 popular US events: Triple Bypass, Unbound Gravel, Levi's GranFondo, Belgian Waffle Ride, SBT GRVL, El Tour de Tucson, Leadville 100, Mt. Washington Hillclimb, and more. Filter by road, gravel, MTB, or hill climb. Add your own custom race anytime. • Ride endurance — set a distance and climbing target by a date ("ride 100 miles with 8,000 ft of climbing by August 30"). We ramp you toward it. • Get faster — no event needed. Pick a focus (increase speed or build general fitness) and a duration (8 / 12 / 16 weeks). Plan rotates intensity blocks every 4 weeks. Personalized to you Three quick questions shape every plan: • Terrain — flat, rolling, or hilly. We bias climbing targets to match where you actually ride. • Ability — beginner, intermediate, or advanced. We cross-check against your last 90 days of Strava history so plans stay honest. • Ride preferences — pick which 3 or 4 days a week you ride and which one is your hardest. We slot prescriptions onto those days. More than just rides Optionally add strength training, stretching & mobility, and sleep & recovery to your plan. Workouts and routines are phase-specific (Base / Build / Peak / Taper) and automatically scheduled around your hard ride days — strength never lands the day before your long ride. • Strength: 2 sessions per week (1 in peak phase) with cycling-specific lifts — Bulgarian split squats, Romanian deadlifts, single-leg work, core stability. • Stretching: short post-ride flush after every ride, plus one longer dedicated session weekly. Hip flexors, hamstrings, T-spine. • Sleep & Recovery: phase-specific sleep targets, contrast-shower protocols, caffeine cutoffs, foam-roll routines. Plan you can actually see • Weekly plan view — expand any week to see prescribed rides, strength sessions, stretching routines, sleep targets, and nutrition guidance for that phase. • Calendar — every workout, ride, lift, and mobility session on one month grid. Tap a day for the full prescription. • Home — your next ride, weather, route suggestions from rides you've done before, weekly stats, speed-for-grade trends. • Race detail — interactive heart-rate and power charts when available, personal records surfaced from your Strava history. Honest about your data • Strava is the only third party. We read your cycling activities. We never write to Strava and we never read messages, segments you've created, or your social graph. • Your Strava access token is AES-encrypted at rest in our backend. • Everything else (profile, goals, preferences, interests) lives only on your iPhone. • No ads. No analytics. No crash reporters. No trackers. • Disconnect any time — tap "Disconnect Strava" in Settings. Tokens are deleted from our backend immediately. Free. No paywall. Built by a cyclist who needed it. Free to use, ad-free. Requires a Strava account to connect.
