The Four-Week Lean Muscle Workout Plan
Follow this tough but rewarding lean muscle workout plan to shock your body into burning fat and building lean muscle
It takes a lot of effort to simultaneously lose fat and build muscle in pursuit of a lean, sculpted physique, but it doesn’t have to take months and months. As long as you have a few years of weights-room experience under your belt, you’ll see results from this challenging lean muscle workout plan after four weeks.
And if you have less experience in the gym? Then the muscle gains will probably come quicker if you follow a suitable beginner gym workout.
How To Follow This Lean Muscle Workout Plan
Each week on the plan you’ll be doing four workouts. Workouts 1 and 3 focus on your upper-body, while sessions 2 and 4 are full-body workouts. This means you’ll be hitting your upper body four times a week to help you bulk up, while also maximising fat loss with tough full-body sessions that fire up the biggest muscle groups in your lower body.
How To Do The Workouts
All four of the workouts are made up of five exercises, but the structure of the upper-body sessions is different from the full-body ones. In the full-body workouts you’ll be doing straight sets throughout, while in the upper-body workouts you begin with straight sets before tackling a tri-set to fatigue your muscles thoroughly.
Do the exercises in the order given below, sticking to the sets, reps, tempo and rest as described. Unless the guide says to use a light weight, use the heaviest one that allows you to complete the exercise with perfect form and aim to increase the weight slightly each week.
Sticking to the tempo given for each move is crucial to maximising the effects of these workouts. Our weightlifting tempo guide goes into greater depth, but essentially the four-digit code indicates how long to spend on each stage of an exercise. The first digit is how long you should take to lower the weight, the second is how long you pause at the bottom of the move, the third is how long for the lift, and then the fourth is how long you pause at the top. A number indicates the seconds you should take, while an X means to do that stage explosively.
