Key Takeaway: It is possible to build muscle with light weights as long as you're doing an adequate amount of volume. This means doing sets of at least 10 reps, though sets of 15 or more are more effective at building muscle with light weights.
3 pounds is hardly enough weight/load to trigger any appreciable upgrades in both size and strength. You'd have to go bigger than that. Muscles generally require heavier loads than they are accustomed to inorder to change.
You don't have to lift heavy barbells to strengthen and tone your arms (though bigger weights can supercharge your sculpting). This lightweight arm workout uses 1- to 3-pound weights and still produces big changes over time.
Alan Aragon, my coauthor on The Lean Muscle Diet, estimates that an entry-level lifter can gain 2 to 3 pounds of muscle mass in a month without adding much fat. An intermediate can gain 1 to 2 pounds a month, and an experienced lifter will be lucky to add a half-pound.
Using lighter weights with higher repetitions might be a more efficient way to build muscle.
For beginners, Ben recommends trying five to 10 pounds for light weights, 10 to 20 pounds for medium weights, and 15 to 30 pounds for heavy weights—or simply starting with five-pound weights for each exercise and working up from there.
One of the most common ways to build arm muscle is to lift weights, but you don't have to bench press hundreds of pounds to strengthen your upper limbs. Light weights can also do the trick, especially if you use the right strategy and have realistic expectations.
Most beginners will see noticeable muscle growth within eight weeks, while more experienced lifters will see changes in three to four weeks. Most individuals gain one to two pounds of lean muscle per month with the right strength training and nutrition plan.
In general, weight gain from fat will result in a softer appearance, while weight gain from muscle will leave you looking leaner and feeling stronger. The most accurate way to assess any change in your body composition is through body composition testing.
Gained 10 pounds in a month? Or yet, gained 10 pounds in a week? Now that's cause for concern. This kind of totally unexplained weight gain can signal more serious health problems such as a hormone condition or a reaction to an Rx.
If you prefer to track progression through weight or reps, try this: Start with 8 repetitions of 3-5 exercises using 3-pound weights. Perform three rounds of all of the exercises in the circuit. Then, after doing this every other day for 2-3 weeks, increase your repetitions to 10. Repeat for 2-3 weeks.
I recommend starting with 5-pound weights. Halfway through the month, do a check-in with your body to see if they feel too light. If so, you can move up to 7.5- or 8-pound weights. If you notice you are building muscle too quickly, or bulking instead of toning, I recommend staying lighter with your weights.
A: 2lb weights are great for arm exercises. The weights don't put too much strain on your muscles, while helping to build basic strength in your triceps and biceps.
Is it OK to do light weights every day? In short, yes. But, Savage says “it all depends on what your personal goals are for your fitness journey. If your primary goal is to maintain strength and muscular definition, then sticking to lighter weights and higher repetitions is perfect for your routine.
If your goal is to build muscle, workouts with reps as low as five and as high as 30 will do the job. We suggest you stick to five to seven reps per set for heavier, compound movement and between eight and 12 reps per set for smaller muscles and single-joint exercises.
2 to 3 Months: After two to three months of consistent strength training, your muscles will become stronger, and you may even notice a slight increase in muscle definition. 4 to 6 Months: You should see and feel your hard work paying off by now, and you will likely feel great about seeing the results!
So even though you may be losing fat, you're gaining muscle. You might feel slimmer, even as the number on the scale rises. “The scale doesn't tell the entire story,” said exercise physiologist Christopher Mohr, PhD, RD. “Since muscle and fat take up different volume, they look very different on the body.”
While the difference was small, this study shows that you can absolutely build muscle even if you have lighter dumbbells. So, tell your 3lb dumbbells to cheer up, they can be just as useful as a 5lb dumbbell.
Downtime between workouts (whether you're lifting, doing cardio or training for a sport) is when our bodies have a chance to actually build muscle. Strenuous workouts cause muscle breakdown, while rest allows our bodies to build it back up.
Tip. To tone your arm muscles, consider starting with 2- to 3-pound dumbbells, all the way up to 5- to 10-pound dumbbells for women and 10- to 20-pound dumbbells for men. Once you can do 12 to 15 repetitions with little effort, it's time to increase the weights.
Rest between set durations should be based on sets/exercise (volume), and not load or training goal. General recommendations include moderate (2 min) rest between sets if performing 2 sets/exercise, long rest (3 min) if performing 3 sets/exercise, and very long rest (> 4 min) if performing 4 sets or more/exercise.
Slow, controlled reps with lighter weight can build muscle better than lifting as heavy as possible.
