Dips vs Tricep Press

I can do around 5 dips but I find it very hard to keep my back level. I think if I did perfect form I could do maybe 2 dips. Is it better right now to work with the tricep press? I can do around 10 sets of 95 and the chair + belt keeps me in good form. I feel like I'm getting more out of this weight exercise.

Unless you're rehabbing an injury: compounds >>> isolation.

Try slow negatives: jump up to the top and slowly lower yourself down, like you would when working towards a pullup. Brutally effective at building up your dipping strength.

Also, you can try greasing the groove with the 2 dips you have now.
