Exercises for chronic kidney disease — KDIGO 2020, walking-first

The 2020 KDIGO (Kidney Disease: Improving Global Outcomes) guidelines made exercise a formal recommendation for CKD stage 3-5 — aerobic + resistance training reduces all-cause mortality, improves cardiovascular fitness, reduces inflammation, and improves quality of life. Walking-based programs are the safest entry — low cardiac stress, no equipment, predictable BP response. The unique constraints for CKD users are: AV fistula or graft arms (if in dialysis transition planning) need protection from heavy compression and high-load weightlifting; BP monitoring is critical because most CKD users are on multiple antihypertensives that can drop BP unpredictably during cardio; anemia from low EPO production reduces exercise tolerance and needs nephrology coordination; bone-mineral metabolism complications mean balance + fall-prevention work is important. Start under nephrology supervision, especially in stage 4-5.

Volya's catalogue carries the foundation: slow-arm-swing-walk and standing-march for the walking-based protocol, seated-march when standing fatigues, wall-push-up for upper-body strength without high spinal load, supported-glute-bridge for joint-friendly glute work, sit-to-stand for functional strength + balance, scapular-retraction for posture, diaphragmatic-breathing for autonomic regulation. The AI coach also knows the nutrition side — protein restriction 0.6-0.8 g/kg in stage 3-5 (nephrologist sets exact target, DON'T self-restrict), potassium restriction if stage 3+ (bananas, oranges, potatoes, leafy greens, beans may need limiting under renal-dietitian guidance), phosphorus restriction (limit cola, processed phosphate additives, dairy, organ meats), sodium ≤2 g, fluid restriction in advanced stages set by nephrologist, AVOID magnesium / calcium supplements without nephrology approval (accumulate in CKD), iron + active vitamin D (calcitriol) managed by nephrology, AVOID NSAIDs (accelerate CKD progression). This is NEVER a replacement for nephrology management — every dietary AND exercise change must be discussed with your renal team.
