How Many Calories Do 100 Leg Lifts Burn? | Core Facts

Calories Burned By 100 Leg Lifts – Realistic Range

Leg lifts sit inside the calisthenics family. Energy cost is usually low to mid for this group. The most cited standard is the Compendium of Physical Activities, which lists 2.8 MET for light core work and 3.5 MET for light-to-moderate calisthenics. Using those bands, 100 reps land inside a small window for most people.

Two things set the total: how much you weigh and how long you take to finish the set. A quick set wraps in about 4–5 minutes. A slow, controlled set can take 7–8 minutes. The tables below use those bookends to keep the estimate honest.

Estimated Calories For 100 Reps By Body Weight

Body Weight	Quick Pace (4–5 min)	Slow/Controlled (7–8 min)
50 kg	11–14 kcal	20–24 kcal
55 kg	12–15 kcal	22–27 kcal
60 kg	13–17 kcal	24–29 kcal
65 kg	14–18 kcal	25–32 kcal
70 kg	15–19 kcal	27–34 kcal
75 kg	17–21 kcal	29–36 kcal
80 kg	18–22 kcal	31–39 kcal
85 kg	19–23 kcal	33–42 kcal
90 kg	20–25 kcal	35–44 kcal
95 kg	21–26 kcal	37–47 kcal
100 kg	22–28 kcal	39–49 kcal

These are ranges, not single points. A taller frame or a very deliberate tempo pushes you to the top of the range. A shorter frame or fast cadence lands near the lower edge.

How The Math Works

Energy burn from movement often uses a simple formula tied to METs. The equation is MET × 3.5 × body weight (kg) ÷ 200 = calories per minute. The Compendium bands above supply the MET. Time on task gives the minutes.

Example: 70 kg person, steady pace, six minutes, MET 3.0. Plug it in: 3.0 × 3.5 × 70 ÷ 200 × 6 ≈ 22 kcal. Shift the MET to 3.5 and you get ≈ 26 kcal. Stretch the set to eight minutes at 3.5 MET and you reach ≈ 34 kcal.

Why MET bands? Leg lifts vary. Lying leg raises feel different from standing abduction. Hanging leg raises demand more bracing. A single label would mislead. The bands keep the estimate fair.

Why The Number Changes

Body Weight Matters

MET math scales linearly with mass. Add 10 kg and the per-minute number climbs in lockstep. That is why two people moving the same way for the same time do not land on the same total.

Pace And Time Under Tension

Reps alone can hide effort. A rushed set trims minutes. A crisp down-and-up may last two seconds. A slow lower with a hard pause stacks tension and minutes. Longer tension equals more minutes and slightly more burn.

Form And Variation

Small tweaks change the cost. Bent knees ease the lever. Straight legs extend the lever. A tiny posterior pelvic tilt ties the move to your lower abs and asks more from your trunk. Hanging adds grip and hip flexor load. Weighted cuffs add load at the ankle and bite a little more.

Rest Between Mini-Sets

Many lifters split 100 reps into chunks. Short rests keep heart rate up and minutes ticking. Long rests cut minutes and drop the total. If you pause, keep the clock in mind when you compare days.

Trusted Reference Points

The Compendium of Physical Activities groups core drills like curl-ups and planks at 2.8 MET and labels light-to-moderate calisthenics at 3.5 MET. A long-running chart from Harvard Health shows similar ballpark numbers for calisthenics across three body weights.

Quick Way To Personalize Your Estimate

Step 1 — Time Your 100

Run one honest set and time it. Note whether you used straight legs, bent knees, or a hanging station. Write the minutes down.

Step 2 — Pick The MET Band

Use 2.8 if the set felt like gentle core work. Use 3.5 if it felt like a steady calisthenics set. If you used a hanging station or ankle weights, use the upper edge.

Step 3 — Do The One-Line Math

Multiply MET × 3.5 × your weight in kg ÷ 200 × minutes. That gives a clean estimate. Round to the nearest whole number for logging.

Calories Per Minute During Leg Lifts

The table below uses the Compendium bands to show calories per minute at two efforts. Pick the row closest to your scale number. Multiply by your set length.

Body Weight	Light Effort (2.8 MET)	Light–Moderate (3.5 MET)
50 kg	2.4 kcal/min	3.1 kcal/min
55 kg	2.7 kcal/min	3.4 kcal/min
60 kg	2.9 kcal/min	3.7 kcal/min
65 kg	3.2 kcal/min	4.0 kcal/min
70 kg	3.4 kcal/min	4.3 kcal/min
75 kg	3.7 kcal/min	4.6 kcal/min
80 kg	3.9 kcal/min	4.9 kcal/min
85 kg	4.2 kcal/min	5.2 kcal/min
90 kg	4.4 kcal/min	5.5 kcal/min
95 kg	4.7 kcal/min	5.8 kcal/min
100 kg	4.9 kcal/min	6.1 kcal/min

Technique Tips That Keep The Work On Target

Brace First

Exhale, tuck the ribs down, and flatten the low back to the floor before the first rep. This trims sway and keeps the work in your trunk, not your hip flexors.

Control The Lower

Think smooth lowering and no bounce at the bottom. A one-second pause below cuts momentum and builds better reps.

Match Range To Strength

Tap the floor only if your back stays flat. If the pelvis tips forward, shorten the path. Clean reps beat sloppy full range every time.

Ways To Adjust Difficulty

Make It Easier

• Bend the knees to shorten the lever.
• Use a light head lift to cue the brace.
• Split into five sets of 20 with short rests.

Make It Harder

• Straighten the legs and slow the lower.
• Add a brief hold at 45 degrees.
• Use ankle weights or try a hanging station.

Building A Small Core-Focused Finisher

Want a tidy add-on at the end of training? Try 50 lying leg raises, a two-minute forearm plank, then 50 more leg raises. Expect total time near eight to ten minutes. Your number will line up with the top end of the range above. If you prefer to stand, swap in standing cable hip flexion for the second block and keep the clock running.

When A Calorie Count Is Not The Goal

Leg lifts shine as a trunk builder. The main win is better control of the pelvis and rib cage. That win carries to running, squats, and deadlifts. The calorie total is small compared to a brisk walk, a rower, or loaded carries. Use the move for strength and control, and pair it with longer bouts of rhythmic work for a bigger burn.

Common Mistakes That Skew The Estimate

Racing The Set

Speed cuts minutes and trims the total. It can also shift the stress to the back. Smooth tempo gives a cleaner number and a better training effect.

Holding The Breath

That habit blunts your pace and shortens sets. Use a gentle breath out on each lift. Your brace will feel stronger and the cadence will settle.

Random Breaks

Long pauses reset the clock. If you split sets, keep rests short and consistent. That way your estimates match session to session.

Putting It All Together

For most people, 100 leg lifts burn roughly 12–35 calories. Lighter bodies and quick sets live at the low end. Heavier bodies and slow, controlled sets sit at the high end. The Compendium’s 2.8–3.5 MET band explains the gap and keeps the math simple. Time your set, pick the band, run the one-line equation, and log the result with a short note about your variation.

Why Track This At All?

Some days you want a number to balance a food log or to keep a streak alive. A small, consistent method beats fancy tools for this. Use one variation, keep cadence steady, and write down weight and minutes each time. Over a few weeks you will see a pattern. The pattern is the value.

Sample Mini Workout With An Estimate

Try this simple block when you have limited time. Do 25 lying leg raises, rest 20 seconds, then 25 more. Walk for two minutes. Finish with 50 leg raises. Total work time lands near seven to nine minutes. A 70 kg person using the 3.5 MET band would hit roughly 30–34 kcal for the leg raises plus about 10 kcal for the short walk. Light, tidy, and easy to repeat. Log it the same way next week for clean comparisons.
