Hey,can you please tell me how it is possible to do progressive load with dumbell shoulder press because the dumbells go up with 2 kg? My 15 RM is about 14 kg.When i will start with 2 weeks of 15's i should start with 75% of 14kg..that will be 10.5kg..how is this possible??? And so on with 80%,that will be 11.2kg.Never seen such dumbells.Should i then only do workouts with barbells?Seems to me then so limited because i like and prefer dumbells.Can you also please tell me how to start a thread in a forum,i am new to this.Thanks in advance!
