Isometrics can be a real WEAPON in your training arsenal, but like anything else, you have to apply them properly!
What are Isometrics?
Glad you asked!😎
During any given movement, the muscle fibers lengthen (stretching during the eccentric phase), and then shorten (contracting during the concentric phase).
An isometric contraction consists of a muscular contraction that involves no movement from the relevant joint.
Typically these are done at the point of the range of motion where the tension is the GREATEST! 🔥
Here are some tips to best utilize isometrics in your training:
▶️Do them with a relatively “heavy” load for time periods of :30 or less. The real benefit of isometrics lies in the fact that there is a MAXIMAL muscular contraction, but in order for that to occur, it can’t feel like you are “hanging out” while performing them for long periods of time. Anything longer than :30 will likely tap more into muscular endurance, and that is a different physical quality that is not our focus here.
▶️Use them on a given muscle group BEFORE it is fatigued, in order to take advantage of using a sufficient enough load. This will recruit a large number of motor units, which is the goal for strength and size development. All too often, they are used as a “finisher”. This is not a bad thing, per se, but if you have not tried them fresh, give it a whirl!
▶️Use them at YOUR weakest moments in a given lift OR where tension is greatest.
Weak at the bottom of a squat?
Use them there!
Tend to feel the most pec tension in the midpoint of your press?
That’s your spot!
