Go heavy or go home
Saturday, March 29th, 2008For the past year I’ve lowered my rep range to 8-12 and focused on lifting heavier. For the longest time, I followed what the fitness magazines suggest and kept my reps in more of a 12-15 range, with occasional high reps (20-25). But after I started seeing a more toned and leaner me, I’ve abandoned the high rep philosophy. Except when it comes to bodyweight exercises (like pull-ups, push-ups, dips), then I just do as many as I can. I should also clarify that I also use very slow and controlled movement. The eccentric part of the contraction is 3-5 counts, and I start with the eccentric contraction if possible. The concentric contraction is typically a one count.
The other benefit I’ve realized is greater strength. I reached a new 10 rep max for DB chest press… now up to 30 lb DBs! About 1 year ago I was using 15s or 17s. This has also improved my BW exercise muscle endurance. I can now bust out 6 chin-ups (underhand grip)… as opposed to maxing out at 4. Also, today I did 10 dips (going really low)… as opposed to maxing out at 7 or 8.
Using the heavier weight/lower rep method can also increase calorie expenditure. Your muscles require more oxygen and the more oxygen you process… the more calories you burn. But the calorie expenditure doesn’t end there… muscle mass increases metabolism. So the more muscle mass one has, the more calories burned throughout the day.
Based on my own success with lifting heavier, I encourage my group fitness followers to do the same. After we complete one set of a particular exercise, I tell them if they were able to easily complete set 1, they need to go heavier in set 2. At the gym today, I saw a gal (I know) doing assisted pull-ups and she just kept going and going. I suggested she reduce the weight so she is forced to lift more of her BW and do fewer reps. She reduced the stack by two plates and was able to do 7 reps! She was excited and encouraged that she could do it. Needless to say, she was convinced to start lifting heavier.
Now, I’m not saying that high rep ranges are not effective and I do them every once in a while to shock my muscles. I primarily do them with BW exercises and every now and then I do Tabata rounds. But as a general rule… the target is 10 reps. If I can do 12-15, then it is time to up the weight. And no matter what, low or high reps, slow it down. Give it a try and LMK how you do. Or perhaps you’ve learned what I have.
