Lean-cut metabolic finisher

I'm an intermediate lifter in a calorie deficit and want a 15-minute metabolic finisher circuit I can do after weights, 2-3x/week, to add training volume without crushing my recovery. Keep it joint-friendly and treat it as conditioning, not a substitute for my lifting. Structure it like this: Warm-up (3 min): 30s easy march, 30s leg swings each side, 30s bodyweight squats, 30s arm circles, 30s glute bridges, 30s jumping jacks. Main circuit (10 min): 4 stations, 40s work / 20s rest, 2 rounds through, target RPE 7-8 (hard but I can keep good form): 1) Kettlebell or dumbbell swings (hinge, snap hips) 2) Goblet squats with a moderate dumbbell 3) Push-ups (elevate hands if needed to keep form) 4) Mountain climbers or low-step-overs Give me a 1-minute walking reset between the two rounds. Cooldown (2 min): easy walk + 2 standing stretches with 20s holds. For each station give me a one-line form cue and a regression and a progression. Tell me a heart-rate target range (rough % of max) for the work intervals. Remind me that fat loss comes from my overall calorie deficit, not this circuit specifically.
