Celebrity trainer Siddhartha Singh, known for working with actress Tamannaah Bhatia, shared a 45-minute full-body routine built for people who keep saying they have “no time to work out”.

The idea is simple. In under an hour you:

• Hit all major muscle groups
  
  

• Get a dose of cardio
  
  

• Use supersets so you spend more time moving and less time resting
  
  

Done 2 to 3 times per week, this kind of session fits neatly within global exercise guidelines and can help you work toward weight-loss and fitness goals without living in the gym.

Why 45 minutes can be enough for weight loss

You do not need marathon sessions to see results. What matters is total weekly activity, intensity and consistency.

Guidelines from organisations like ACSM and the CDC recommend about 150 minutes of moderate-intensity activity per week, plus 2 or more strength sessions.

A 45-minute routine like this, done three times per week, gives you:

• Around 90 minutes of strength-focused work
  
  

• About 45 minutes of dedicated cardio
  
  

• A strong foundation to build on with daily walking and general movement
  
  

Superset training, where you pair two exercises back to back, has been shown to deliver similar strength and hypertrophy benefits to traditional training in significantly less time, while increasing workout density and calorie burn.

In other words: if you work with purpose, 45 minutes is plenty.

How this 45-minute full-body workout is structured

Singh’s routine is split into three strength supersets (about 30 minutes) followed by 15 minutes of incline walking on the treadmill.

Before you start, take 3 to 5 minutes to warm up with:

• Easy treadmill walking or cycling
  
  

• Gentle joint circles for hips, shoulders and ankles
  
  

Then move into the main session.

Superset 1: Upper body push and pull

A1. Push-ups

• Focus on a straight line from head to heels
  
  

• Lower with control, avoid letting your hips sag
  
  

• Aim for about 12 reps, or as many good-form reps as you can manage
  
  

A2. Close-grip seated pulldown

• Hands closer than shoulder-width
  
  

• Pull the bar toward your upper chest, squeeze your back at the bottom
  
  

• Again, aim for around 12 reps
  
  

Move directly from push-ups to pulldowns without resting. That pairing hits chest, shoulders, triceps, lats and upper back in one time-efficient block.

Rest 60 to 90 seconds after each superset. Repeat for 3 rounds.

Superset 2: Legs and posterior chain

B1. Goblet squats with elevated heels

• Hold a kettlebell at chest level
  
  

• Stand with heels slightly raised on plates or a small wedge
  
  

• Squat down, keeping your chest proud and knees tracking over toes
  
  

• Target 12 controlled reps
  
  

Elevating the heels shifts more emphasis to the quadriceps and can feel friendlier for tight ankles.

B2. Dumbbell deadlifts

• Hold a dumbbell in each hand
  
  

• Hinge from the hips, push them back while keeping your spine neutral
  
  

• Feel the tension in your hamstrings, then drive through your feet to stand tall
  
  

• Aim for 12 reps, slow on the way down
  
  

Do both exercises back to back, then rest 60 to 90 seconds. Complete 3 rounds.

Superset 3: Core and calves

C1. Hanging knee raises

• Hang from a bar with a firm grip
  
  

• Bring your knees toward your chest without swinging
  
  

• Lower with control
  
  

• Aim for 10 to 12 reps
  
  

If full hanging raises are too tough, you can start with:

• Bent-knee raises from a captain’s chair
  
  

• Lying knee tucks on a mat
  
  

C2. Calf raises on the leg press

• Sit in the leg press with the balls of your feet on the platform edge
  
  

• Keep your knees slightly bent
  
  

• Push through your toes to lift your heels, then lower slowly
  
  

• Aim for 20 reps, focusing on full range and strong contractions
  
  

Pair the two movements without resting, then take 60 to 90 seconds off. Repeat for 3 rounds.

Cardio finisher: 15-minute incline walk

With around 30 minutes of supersets done, you finish with a simple cardio block:

• Treadmill set to a brisk walking speed

• Add a challenging incline that makes you breathe harder but still allows conversation
  
  

• Walk for 15 minutes continuously
  
  

Incline walking raises heart rate, increases calorie burn compared with flat walking and is easier on the joints than running.

Why this workout uses supersets

Supersets are the backbone of this routine. The trainer designed it so each pair of exercises:

• Cuts down on idle rest
  
  

• Keeps your heart rate elevated
  
  

• Trains opposing or complementary muscle groups in one block
  
  

• Makes a 45-minute session feel purposeful, not rushed
  
  

Studies and expert reviews highlight that superset programming can:

• Increase time efficiency
  
  

• Maintain or nearly match strength gains compared with traditional sets
  
  

• Boost metabolic stress, which supports muscle growth and fat loss when combined with proper nutrition

For busy people, that combination of efficiency and effectiveness is exactly what you want.

How to scale this routine to your level

You do not have to match a celebrity’s trainer on day one. Adjust the plan to your current fitness.

If you are a beginner

• Do 2 rounds of each superset instead of 3
  
  

• Use incline push-ups instead of floor push-ups
  
  

• Choose lighter kettlebells and dumbbells you can control
  
  

• Swap hanging knee raises for lying knee tucks
  
  

If you are more advanced

• Add a third or even fourth round of certain supersets
  
  

• Use slightly heavier weights while keeping technique tight
  
  

• Slow the lowering phase of each rep to increase time under tension
  
  

• Push your incline or speed slightly during the treadmill block
  
  

If you want help integrating this into a weekly plan with other strength and cardio days, you can pick ideas and templates from the GymNation Fitness Hub which offers structured training guidance for different goals and levels.

Using this workout for weight loss (without burning out)

This routine is a strong tool for weight loss, but it works best alongside smart lifestyle choices.

Focus on:

• A moderate calorie deficit, not extreme crash diets
  
  

• Enough daily protein to support muscle as you lose fat
  
  

• Non-exercise movement like walking, stairs and standing more
  
  

To get a sense of your maintenance calories and set an appropriate deficit, try the GymNation fitness calculators then pair those numbers with 2 to 4 weekly workouts and consistent daily movement.

Remember, as Siddhartha Singh stresses, the real goal is consistency, not perfection. A solid 45 minutes you can repeat beats a “perfect” plan you only follow for a week.
