Duration: 25 Minutes | Difficulty: Level 2 — Intermediate | Focus: Lower Body | Type: Cutting

Your lower body houses the largest muscle groups you've got — quads, glutes, hamstrings, and calves. That means it's also your most powerful fat-burning engine. Every squat pulse and reverse lunge you grind through demands enormous energy expenditure. This 25-minute bodyweight lower body circuit is optimized for the cut: high volume, short rest, and compound movement patterns that spike your heart rate while preserving lean mass.

Fuel This Workout

Lower body work demands more glycogen than upper body training. On a cut, this is where most dieters fail — they under-fuel and can't complete the volume, then blame the workout.

Pre-Workout (60–90 min before)

Timing	Meal	Calories
90 min before	Rolled oats (1/2 cup dry) + 2 tbsp peanut butter + 1/2 banana	~380 kcal
60 min before	Katabolic Pre-Workout (1 scoop)	~5 kcal
30 min before (fasted)	1 cup rice cakes (2 cakes) + 1 tbsp almond butter + black coffee	~160 kcal

Post-Workout (within 30 min)

Timing	Meal	Calories
Immediately	Katabolic Whey Isolate (1.5 scoops) + 1/2 banana blended with water	~250 kcal
45 min after	Salmon (5 oz) + roasted sweet potato (1 cup) + steamed asparagus	~450 kcal
2 hours after	Hard-boiled eggs (2) + 1 oz almonds	~250 kcal

Hydration Table

Phase	Fluid	Electrolytes
Pre-workout	16–20 oz water	100mg sodium
During	8–12 oz water every 15 min	200mg sodium, 100mg potassium per 32 oz
Post-workout	20–24 oz water	300mg sodium, 150mg potassium

Calorie deficit tip: Post-workout satiety matters more on a cut than post-workout anabolism — because the biggest threat to your deficit is late-night snacking. The post-workout meal above is designed with protein (salmon + eggs), low-glycemic carbs (sweet potato), and volume (asparagus) to keep you full for 4–5 hours. Don't skip the vegetables — they're doing more for your cut than the protein macros are.

Tips & Modifications

Beginner (Level 1):

Reduce squat pulses to 12 reps
Perform reverse lunges with a shorter step (45° knee bend instead of 90°)
Do glute bridges without the march — just standard bridges 3x15
Complete 2 rounds instead of 3

Intermediate (Level 2):

Stick to prescribed reps
Add a 2-second pause at the bottom of every squat pulse
Use a 4-second negative on calf raises

Advanced (Level 3):

Add a 10-lb weight vest or loaded backpack
Turn sumo squat holds into sumo squat pulses (continuous up-down for 20 reps)
Reduce rest between rounds to 30 seconds
Complete 4 rounds total
Add 10 jump squats after each round (explosive finisher)

Avoiding knee pain on a cut: Fat loss can expose biomechanical issues that extra bodyweight previously masked. If your knees ache during lunges, reduce the step-back distance and keep the front knee tracking directly over the second toe. Never let the knee cave inward.
