FORCED REPS
"You can encounter on problem with cheating reps," notes Dr. Franco Columbu (Mr. World, Mr. Universe, and twice Mr. Olympia). "In cheating up the weight in barbell curls or some other bodybuilding exercise, you will find it difficult to impart just enough momentum to the bar to get it past the sticking point. Sometimes you will generate too much momentum, and the bar will virtually leap up to the finish point at your shoulders, requiring little or no biceps muscle contraction. Other times, you might impart too little momentum to the bar, and it will stall out just short of the sticking point, again yielding little or no meaningful biceps muscle contraction. The trick is to impart just enough momentum to the bar to squeeze it past the sticking point, after which you complete the movement solely with biceps strength rather than momentum."
Dr Columbu continues, "The best way to solve the problem with cheating reps is to remove just enough weight from the bar to allow completion of a repetition past failure...To illistrate forced reps in action, load up a bar resting on the support rack of an incline bench, setting it with a poundage that allows you to complete no more that 7-8 full positive and negative reps in strict form. With your training partner standing by, take your grip on the bar, then have him assist you in taking the bar from the rack and bringing it to the starting point at straight arms' length directly above your chest. Start to grind out each repetition in perfect biomechanical form, doing full, solid reps to the point of failure."
"The moment you fail partway up on a repetition," explains Dr. Columbu, "your training partner should grasp the middle of the bar and pull upward with exactly the correct amount of force necessary to help you complete a forced repetition with the effectively lighter barbell. For the sake of illustration, you might have failed with 225 pounds, but still have sufficient strength and endurance to do a rep with 210, so your partner pulls up hard enough on the bar to allow the next forced rep."
"In the same manner, you can complete a second forced repetition, and in some cases a third one. Obviously, your pecs, front delts, and triceps will be growing progressively more fatigued with each succeeding forced rep, so your training partner will be forced to pull upward on the bar with progressively more force. Ultimately, after two or three of these forced reps, your chest, shoulder, and arm muscles will be so fatigued that you won't vbe able to force out any additional repetitions." Dr. Columbu concludes, "At that point, you can terminate your set secure in the knowledge that you have pushed your working muscles far past the failure point, therby generating a great deal of muscle hypertrophy."
DESCENDING SETS
A third way to push a set past failure is available if you have two training partners. Descending sets, also called "stripping sets" were used by Arnold Schwarzenegger, seven-time Mr. Olympia.
Descending sets are started by stacking equal amounts of ten and and five pound plates on both sides of the bar, but leaving the clips off. While training to failure, your partners remove matching weights off each side of the bar so you can continue to pound out reps. This technique is only for advanced bodybuilders, as it can be dangerous...so be cautious and prudent!
Arnold Schwarzenegger offers some suggestions for doing descending sets without training buddies handy to strip of the weights. "With selectorized weight stacks, you can instantly move the pin up the stack each time you need to strip weight. Alternatively, you can go down the rack on various dumbbell movements, using successively lighter dumbbells each time you need a weight drop."
Research recommends that the best gains with descending sets can be seen by doing no more than 2-3 weight drops, always on basic exercises such as bench presses. This highly intense formula can reap some awesome results when done correctly.
BURNS
Forced Reps require one partner to spot you. Descending Sets require two...but what if you happen to be training alone? Burns are the perfect thing for you! Burns profess the use of quick, short partial repetitions after one can no longer complete an additional full rep in strict form.
Examples:
- Calves
- Do a set of standing calf machine heel (hell?) raises to positive failure.
- When you can't make it more than half way up, bring your heels way down...to a bottom position which stretches your calf muscles.
- Rapidly bounced from this position upward as high as possible then back down for 8-12 burns (they don't call them burns for nothing).
- Those heels should move 2-3 inches each time, forcing the calves to work extremely hard past the point of normal failure.
- Heavy calf fatigue will cause you to terminate the set. Do not do more than 12-15...if you can do more then you need to push your first set harder to positive failure!
- Preacher Curls
- Do six complete reps with a heavy barbell.
- Immediately do six burns at the bottom of the set...ouch!
Burns can be done on just about any exercise. There is also a variation of burn which are performed at the finish point of an exercise rather than the starting point. For this variation, you should push yourself until about 90% failure, then get 10-15 burns at the finish point. These are best performed on peak contraction movements...here are some examples:
- Leg Extensions
- Leg Curls
- Various types of Rows
- Chins
- Variations of Lat Machine Pulldowns
NEGATIVE REPS
Sometimes referred to as "retro-gravity" reps, negative reps offer some outstanding benefits such as increased muscle mass and physical power. The negative phase of an exercise is the lowering phase. It requires two sturdy training partners.
Example:
Bench Press
- Warm up your pectorals, anterior deltoids, and triceps on a basic exercise such as the bench press.
- Load the bar with approximately 130% of your max bench for one repetition.
- Lying on your back on a flat bench, correctly place your grip on the bar and have your partners lift the weight above you so that your arms are fully extended above your shoulders.
- From there, slowly lower the weight to your chest pushing greatly against the weight trying to slow it down or even stop the descent.
- When it reaches your chest, your partners should lift it back to starting position (arms extended).
- The rest interval should be between 30 and 60 seconds. Do your second negative rep the same way.
- Complete 8-10 of them.
- To avoid overtraining, don't do negative reps every workout. Instead, do a negative-reps-only workout between every 3-4 normal workouts.
- This will greatly accelerate your gains in muscle mass, power, and quality.
OTHER FORMS OF NEGATIVE REPS
These can be done by yourself or with only one training partner.
- "Negative Emphasis"
- Simply slow down the negative cycle of the exercise so that it takes twice as long as normal to complete a repetition. (If you normally raise a weight in 3 seconds and lower it in 5, instead raise the weight in 3 seconds and lower it in 10 seconds.)
- "Negative Assisted Reps"
- These can be performed only on various types of machines. They involve lifting the weight normally for the positive phase, but for the negative phase only using one arm or one leg, resisting mightily against the descent.
- For example:
- Standing Calf Machine Calf Raises:
- Choose a weight that you can lift normally 15 times.
- Lift the weight 6-8 times to warm up.
- Continue your set by pushing up with both legs, then lowering with only one leg.
- Alternate legs each time you lower the weight, switching to the opposite leg.
- Powerfully resist the negative movement and continue the set until complete muscle failure.
- Pain is a good thing...in this case your calves will become denser quicker.
- Universal Machine Bench Presses:
- Follow the procedure above, using only one arm to push against the negative portion of the rep.
- Alternate to the opposite arm after each positive lift.
- "Forced Negative Reps"
- The fly machine will be a good illustration:
- Choose a weight in which you can get only 6-8 full repetitions.
- Your training partner should be positioned in front of you.
- Start by doing 6-8 reps to positive failure.
- As soon as you fail, have your partner give you a forced rep.
- Then during the negative portion of the rep, have your partner give some force on the pads, actually pushing them apart, while you try and hold them back.
- With your partners extra resitance, these negative reps will be extremely effective in increasing muscle mass.
- This variation of forced negative reps can be done on many machines and some free weights.
