Quick one today — just dropping some ideas for your KB off days.

These are what I call “500 Calorie Engine Builders” — conditioning sessions designed to burn an extra 500 calories on the days you’re not swinging a kettlebell.

Two categories depending on how your body feels that day. Grinding and beat up? Go green. Got gas in the tank? Go red.

7 “kettlebell off-day” workouts (HIIT + LSD)

GREEN – LSD (Low Intensity, Steady State)

1. Weighted ruck — 20–30 lb pack, 30–45 min, moderate pace. Flat or hilly terrain both work.
2. Recovery jog — 20–30 min, slow enough that you could hold a full conversation. No watch, no pace target.
3. Incline treadmill walk — 30–45 min, 8–12% incline. Slow and steady wins here.

RED – HIIT (High Intensity Intervals)

1. Hill sprints — sprint hard to the top, walk down for recovery. 6–10 reps. Grade should be steep enough that it hurts.
2. Assault bike sprints — 20 sec max effort / 40 sec easy pedal. 10–15 rounds. Arms and legs both driving on the hard intervals.
3. Sprint / walk alternates — sprint 20–30 sec all out, walk 90 sec. 8–10 rounds. Flat ground or track.
4. Fast run + KB swings — run 200–400m at 80% effort, then 20 KB swings immediately. Rest 2 min. 5–6 rounds.
