CORNERAI REPORT — MARCUS · INTERMEDIATE · SPARRING
April 8, 2026 · Session #12 · 3 rounds analyzed
╚══════════════════════════════════════════════════════════╝
OVERALL SCORE: 74/100
Defense: 61 · Offense: 82 · Footwork: 74 · Head Movement: 67
WHAT YOU'RE DOING WELL:
✓ Jab volume is high and consistent — you're setting up combinations
✓ Body shots at [1:14] and [2:33] are landing clean, opponent visibly reacting
✓ Lateral movement off the back foot is solid — good angles after combos
TOP MISTAKES TO FIX:
1. [0:18] LEFT HAND DROPS AFTER JAB — every time you jab your left
drops to hip level. This is happening on 80% of your jabs. You are
getting away with it now but vs a faster opponent that's a KO.
2. [1:02] FLAT-FOOTED ON RETREAT — when you step back you're
landing on your heels, no pivot, walking straight into the corner.
You got caught there at [1:09]. Pivot off your back foot instead.
3. [2:15] TELEGRAPHING THE RIGHT HAND — visible shoulder dip
before every cross. Your opponent is already moving at [2:17]
before your punch lands. Shorten the wind-up.
4. [2:58] CHIN UP IN EXCHANGES — under pressure your chin rises.
Spotted 4 times in round 3. This is your highest KO risk.
DRILL PRESCRIPTIONS:
→ Jab & Return Drill: 4x3min on mitts — hand snaps back to cheek every rep
→ Pivot Retreat Drill: 3x2min — no straight backward steps, pivot only
→ Resistance Band Jab: 100 reps daily — eliminates the shoulder telegraph
→ Chin Tuck Shadowboxing: 3 rounds with tennis ball under chin, non-negotiable
COACH'S NOTE:
Marcus — your offense is genuinely good. You're landing, you're
busy, and your body work is hurting people. But that guard drop
after the jab is happening every single round and you don't even
know it. Fix that one thing and your score jumps 10 points minimum.
Chin tucked. Hand back. Every. Single. Jab.
