Table 3. The accuracy of the 6RM prediction equations (n = 29).

Equation	Mean difference (actual load - predicted load)	MAPE(%)
Hammer curl = Bench press (0.28) + 6.30kg	.42kg *	8.54
Barbell biceps curl = Bench press (0.33) + 6.20kg	.37kg *	6.52
Overhead triceps extension = Bench press (0.33) - 0.60kg	.54kg *	7.78
Dumbbell shoulder press = Bench press (0.42) + 5.84kg	.29kg *	7.05

* Not significant in t-test comparison. MAPE = Mean absolute percentage error.
