You have more wisdom than you did when you were a young man from all your years of experience-but in some settings, like the gym, you'll need to adjust your behavior to keep up with the changes that happen to your body when you age. That's why men over 40 should take a slightly different approach to fitness than their younger peers, with an emphasis on careful, calculated programming.

The Men's Health Muscle After 40 book gives you that smart, measured plan you need for your workout as an older man.

The 12-week fitness guide doesn't give you handicapped workouts with instructions to play it safe-the plan is designed to bring out the best in you while allowing you to rest and recover within your body's capacity. Muscle After 40 is split into 3 distinct phases, each of which consist of 3 weeks where you'll train 3 times.

This is Phase 1, Week 1.

Warm Ups

If you know what works best for you, keep doing it. That said, if what you do is walk into the weight room and start lifting with no warmup at all, I predict it wont work for much longer. The older you get, and the more miles you put on the chassis, the trickier it is to get your body ready for a good workout.

Your warmup should at least have these two components:

• A general warmup to increase core temperature, heart rate, and blood flow. Youll probably need more time for this if you train in the morning versus the evening, or winter versus summer. Light cardio, mild calisthenics, mobility exercises, or some combination will to the trick.
• A specific warmup for the first exercise, or pair of exercises, in your workout. Again, this can be a comprehensive mobility routine, a few practice sets of the exercise with light weights, or a combination of both.

What You'll Need

This program requires basic equipment youll find in most commercial gyms. Dont worry if your gym doesnt have everything on the list. Its easy to substitute similar exercises.

Full range of dumbbells, including weights that seem much heavier than anything youd consider lifting right now

• Barbells (Olympic and EZ curl) and weight plates
• Flat and incline benches
• Landmine
• Squat rack
• Cable tower
• Leg press, leg extension, and leg curl machines(calf raise machine is optional)
• Kettlebells
• Ab wheel

Overview

You'll train three times a week for four weeks. Most will use the classic Monday-Wednesday-Friday or Tuesday-Thursday-Saturday schedule. Remember to include at least one full day of rest between workouts. Youll do each exercise as straight sets, completing all the sets of one exercise before moving onto the next.

Weight Selection

For the first exercise on Day 1 (dumbbell incline bench press) and Day 2 (trap-bar deadlift) youll use the sets across method, which means youll use the same weight for all your work sets. (Its the opposite of ramping sets, in which you use a heavier weight on each set, building up to a final set with a max weight.) With the sets across method, you dont increase the weight until you hit all the reps on every set.

Lets say youre doing 3 sets of 6 to 8 reps. After doing a warmup set with a lighter weight, you select a weight you figure you can lift 10 times. You easily complete 8 reps the first set, and couldve done at least two or three more. On the second set, you also get 8 reps, although this time you only have one or two left in the tank. On the third set, you can only complete 7.

The next week, you use that same weight for all your sets, with the goal of getting 8 good reps on each one. More important, you feel like you couldve completed at least one or two more on every set. That means youre cleared to increase the weight by 2.5 to5 percent for the following week.

With the rest of the exercises in Phase 1 that are not indicated as using the sets across method, you can use more weight on subsequent sets if your first-set weight was too light and you easily completed all the reps. Increase the weight when you exceed the range by 2 or 3 reps on every set. So if the workout calls for 2 sets of 12 to 15 reps, and you hit 17 or 18 on the final set, use a heavier weight the next time you do that exercise.

Rest

In Phase 1 and Phase 2, I dont specify how to long to rest between sets or exercises. Here area couple of guidelines to follow:

• Dont start a set while youre still catching your breath from the last one. You want to feel like youre at full strength each time you pick up the weights.
• If you feel like you can go straight into the second or third set of an exercise without any rest at all, its a good sign you arent pushing yourself hard enough. Either the weight is too light, or youre doing the exercise in a way that isnt putting tension on the targeted muscles.

Volume

Youll see some progressions in volume within the workouts, specifically the number of sets. With some exercises, youll increase the number of sets (from 2 to 3) after Week 1. Then, in Week 4, youll decrease volume across the board, doing 2 sets of every exercise to give your muscles a break before starting Phase 2.
