The 90-Minute Plan
Align head-to-heels straight. Engage core and glutes. Don't sag hips or pike butt up. Breathe steadily.
Hold plank for 30 seconds. Rest 1 minute. Do 3 sets. Your goal is maintaining perfect form.
Week 1: 30 sec. Week 2: 45 sec. Week 3: 60 sec. Week 4: 75 sec. Week 5: 90 sec. Week 6: 2 min.
Side planks (per side), plank with leg lift, plank shoulder taps. Do 2x weekly with standard planks.
Write down your time weekly. Celebrate PRs. Once you hit 2 minutes, maintain and add intensity.
A strong core prevents back pain and improves posture. Planks are the most efficient core builder.
